Especially, the functions of rGO and CoOOH are studied by using electrochemical impedance spectroscopy, open circuit potentials and intensity modulated photocurrent spectroscopy. [1] Additionally, investigations on dynamic electron transport and recombination properties via intensity-modulated photovoltage/photocurrent spectroscopy (IMVS/IMPS), and electrochemical impedance spectroscopy (EIS) measurements demonstrate that the Zn2SnO4 spheres-based DSSCs possess the fastest electron transport rate, the longest electron lifetime, the highest electron collection efficiency (ηcc), and the largest charge recombination resistance, compared with the Zn2SnO4 plates and particles, all of which are highly beneficial for the powder conversion efficiency enhancements. [2] Electrochemical impedance spectroscopy and intensity-modulated photocurrent spectroscopy, in conjunction with other observations, indicate that the enhanced photocurrent is due to the improved quality of the bottom contact without a noticeable change in the top interface. [3] XRD (X-ray powder diffraction), SEM (scanning electron microscopy), TEM (transmission electron microscopy), UV-vis DRS (diffuse reflectance spectroscopy), XPS (X-ray photoelectron spectroscopy), FTIR (Fourier transform infrared spectroscopy), PL (photoluminescence) spectroscopy, EIS (electrochemical impedance spectroscopy) and photocurrent spectroscopy were used to systematically characterize the as-prepared samples. [4] In order to reconcile these observations, we combine high-dynamic-range TOF photocurrent spectroscopy and energy-resolved electrochemical impedance spectroscopy to extract the hole DOS of the conjugated polymer. [5] From a methodological point of view, we demonstrated, for the first time, that intensity modulated photocurrent spectroscopy (IMPS) and electrochemical impedance spectroscopy (EIS) efficiently complement and can be highly valuable to optimize PEC water-splitting devices. [6] UV–Visible spectroscopy, X-ray photoelectron spectroscopy (XPS), photoluminescence (PL) spectroscopy, Electrochemical Impedance Spectroscopy (EIS), transient photocurrent spectroscopy and Mott-Schottky (M-S) plots were utilized to analyze the band gap and band edge positions of the samples. [7] A comprehensive study of the electron dynamics based on open-circuit voltage decay (OCVD), electrochemical impedance spectroscopy (EIS), intensity-modulated voltage spectroscopy (IMVS), and intensity-modulated photocurrent spectroscopy (IMPS) measurements revealed that the stoichiometric CdS-SG interlayer significantly reduced the charge recombination and prolonged the lifetime of photogenerated electrons in contrast to the CdS-CBD interlayer in the QDSCs. [8] The smallest charge-transfer resistance and the highest electron collection efficiency are also obtained in this case, as examined using the electrochemical impedance spectroscopy and intensity modulated photocurrent spectroscopy/intensity modulated photovoltage spectroscopy. [9] The synthesized ZnO arrayed layers were investigated by using X-ray diffraction, scanning electron microscopy, UV–vis transmittance, electrochemical impedance spectroscopy and photocurrent spectroscopy. [10] The efficient charge separation efficiency was confirmed by the photoluminescence spectroscopy, electrochemical impedance spectroscopy, and photocurrent spectroscopy studies. [11]특히, 전기화학적 임피던스 분광법, 개방 회로 전위 및 강도 변조 광전류 분광법을 사용하여 rGO 및 CoOOH의 기능을 연구합니다.

intensity modulated photovoltage
Moreover, the intensity-modulated photocurrent spectroscopy/intensity-modulated photovoltage spectroscopy (IMPS/IMVS) and electrochemical impedance spectroscopy (EIS) are carried out to investigate the influences of gelation on the kinetic processes of electron transport and recombination in DSSC. [1] The dynamics of carrier recombination and transport of two CuInS2 superstrate solar cells was studied by intensity modulated photovoltage and photocurrent spectroscopy (IMVS and IMPS respectively). [2] Compared to the undoped QDs, Mn-CISe QDSSCs show a shorter electron transport time (τt) and a longer electron recombination time (τr) which are studied by intensity-modulated photocurrent spectroscopy and intensity-modulated photovoltage spectroscopy, respectively. [3]또한, 강도 변조 광전류 분광법/강도 변조 광전압 분광법(IMPS/IMVS) 및 전기화학적 임피던스 분광법(EIS)이 DSSC에서 전자 수송 및 재결합의 운동 과정에 미치는 영향을 조사하기 위해 수행됩니다.

The addition of graphene further improves the dye loading ability of the CuTGR photoanodes with improved current density and faster charge transport as observed in current–voltage (J-V) and intensity-modulated photocurrent spectroscopy (IMPS) measurements. [1] The effects of the Fe2TiO5 interfacial layer are further revealed by X-ray absorption spectroscopy and intensity-modulated photocurrent spectroscopy. [2] To solve the frequency-to-time transformation, we start from models of the transfer function of intensity-modulated photocurrent spectroscopy (IMPS) and derive the associated impulse response function, the transient photocurrent (TPC), in response to a short light pulse. [3] Synchrotron-based characterization techniques, such as grazing incidence x-ray spectroscopy and x-ray fluorescence will be used to understand the structural and chemical composition of the films, whereas intensity-modulated photocurrent spectroscopy will be used to understand transport processes in the devices. [4] Intensity modulated photocurrent spectroscopy and electrochemical impedance spectra results of samples indicated that the surface states at the CZTS/ZnO interface were the recombination centers with the electrons from the CZTS sample and holes from the ZnO and therefore improved its photo-driven salt-water splitting performance. [5] In this work, we conduct a full characterization of DSSCs with the photochromic dye NPI, combining electrical impedance spectroscopy (EIS) and intensity-modulated photocurrent spectroscopy (IMPS). [6] The prominent PEC activity of the hierarchical ZnxCd1-xS nanorod arrays can be ascribed to an enhanced charge transfer rate aroused by the binder-free interfacial heterojunction, and the improved reaction kinetics at the electrode-electrolyte interface, which is evidenced by electrochemically active surface area measurements and intensity modulated photocurrent spectroscopy analysis. [7] We investigate the degradation phenomena of organic solar cells based on nonfullerene electron acceptors (NFA) using intensity-modulated photocurrent spectroscopy (IMPS). [8] Intensity modulated photocurrent spectroscopy (IMPS) shows that, under low applied potential the water oxidation mainly occurs on CoOOH, while under high applied potential the water oxidation could occur on both CoOOH and Fe2O3. [9] Especially, the functions of rGO and CoOOH are studied by using electrochemical impedance spectroscopy, open circuit potentials and intensity modulated photocurrent spectroscopy. [10] We compare the photocurrent magnitude and photocurrent transients using intensity-modulated photocurrent spectroscopy (IMPS). [11] Via intensity-modulated photocurrent spectroscopy analysis, the enhanced mechanism of PEC water oxidation was discovered, that is, the improved surface charge separation efficiency aroused by the increased charge transfer efficiency for the optimized ZFO/MoSx electrode. [12] In this Letter, the role of Ti addition in thick hematite mesoporous photoanodes was elucidated by performing intensity modulated photocurrent spectroscopy (IMPS) monitoring its charge carrier dynamics during water oxidation. [13] Impedance spectroscopy is useful in PLEDs and OFETs and modulated photocurrent spectroscopy is suitable in OPVs for studies of the electronic transport properties. [14] We introduce and apply Fourier transform impedance spectroscopy (FTIS) to a PbS colloidal quantum dot SiC heterojunction photodiode and validate the results using intensity-modulated photocurrent spectroscopy. [15] We carried out in-depth PEC analysis using hole scavenger measurements, PEC impedance spectroscopy, and intensity-modulated photocurrent spectroscopy to elucidate the effect of the surface reduction process upon doping, the impact of Vos, MoOx species and CoOOH layer on the enhanced PEC performance. [16] Intensity modulated photocurrent spectroscopy tests verify that the Ni4O4 cubane catalyst not only facilitates the kinetics of water oxidation, but also suppresses the recombination of carriers at the electrolyte/photoanode interface. [17] Intensity modulated photocurrent spectroscopy (IMPS) is used to investigate the surface carrier dynamics of BiVO4 and BiVO4@Ni:FeOOH. [18] The charge behavior in the CuBi2O4 photocathodes and its relationship with the film thickness are thoroughly investigated by using photocurrent and intensity modulated photocurrent spectroscopy. [19] Electrochemical impedance spectroscopy and intensity-modulated photocurrent spectroscopy, in conjunction with other observations, indicate that the enhanced photocurrent is due to the improved quality of the bottom contact without a noticeable change in the top interface. [20] By combining intensity-modulated photocurrent spectroscopy (IMPS) and numerical simulations, we explore in detail how electron transport and recombination rates as well as the sensitizer regeneration rate affect the steady-state photocurrent and the charge carrier concentration distribution. [21] A further comparison of the charge dynamics by surface photovoltage and intensity modulated photocurrent spectroscopy reveals that the increased surface hole density due to the suppression of charge recombination is account for the improvement in the photocatalytic activity. [22] Moreover, the intensity-modulated photocurrent spectroscopy/intensity-modulated photovoltage spectroscopy (IMPS/IMVS) and electrochemical impedance spectroscopy (EIS) are carried out to investigate the influences of gelation on the kinetic processes of electron transport and recombination in DSSC. [23] Due to the large disparity in results in IS that depends on materials and methods, including the general lack of information obtained in the case of PSCs, Intensity Modulated Photocurrent Spectroscopy (IMPS) measurements were also carried out. [24] However, the role of luminescent coupling in more advanced characterization techniques such as modulated photocurrent spectroscopy is virtually unknown. [25] Intensity-modulated photocurrent spectroscopy (IMPS). [26] Intensity-modulated photocurrent spectroscopy (IMPS) and time-correlated single photon counting (TCSPC) characterization further demonstrate that the PMMA embedded perovskite films have better carrier transport and enhanced carrier extraction rate. [27] From a methodological point of view, we demonstrated, for the first time, that intensity modulated photocurrent spectroscopy (IMPS) and electrochemical impedance spectroscopy (EIS) efficiently complement and can be highly valuable to optimize PEC water-splitting devices. [28] A comprehensive study of the electron dynamics based on open-circuit voltage decay (OCVD), electrochemical impedance spectroscopy (EIS), intensity-modulated voltage spectroscopy (IMVS), and intensity-modulated photocurrent spectroscopy (IMPS) measurements revealed that the stoichiometric CdS-SG interlayer significantly reduced the charge recombination and prolonged the lifetime of photogenerated electrons in contrast to the CdS-CBD interlayer in the QDSCs. [29] The mechanisms of photoelectrochemical water and methanol oxidation on TiO2 anatase (101) and rutile (110) surfaces have been studied using the intensity modulated photocurrent spectroscopy (IMPS) technique. [30] The intensity modulated photocurrent spectroscopy shows that the improved photocurrents and early onset potentials of exfLDH/α‐Fe2O3 photoanode are attributed to fast charge transfer and, more importantly, suppressed charge recombination due to passivation of α‐Fe2O3 surface by the LDH monolayer sheet. [31] The smallest charge-transfer resistance and the highest electron collection efficiency are also obtained in this case, as examined using the electrochemical impedance spectroscopy and intensity modulated photocurrent spectroscopy/intensity modulated photovoltage spectroscopy. [32] By analyzing the PEC responses under various monochromatic lights, PEC impedance spectroscopy, and intensity-modulated photocurrent spectroscopy, we ascribe the improvements to the fact that the suitable-thickness Al2O3 can passivate the Si microwire surfaces and the bottom surfaces of the α-Fe2O3 film and give rise to Al doping into the post-synthesized α-Fe2O3. [33] In addition, this codoping protocol does not introduce additional surface trap states, as evidenced by the increased charge injection efficiency and surface kinetic analysis using intensity modulated photocurrent spectroscopy (IMPS). [34] Small perturbation techniques such as intensity-modulated photocurrent spectroscopy (IMPS) have become an essential tool to unravel the complex, interrelated processes that govern the charge carrier dynamics in photoelectrochemically active materials for solar water splitting. [35] Compared to the undoped QDs, Mn-CISe QDSSCs show a shorter electron transport time (τt) and a longer electron recombination time (τr) which are studied by intensity-modulated photocurrent spectroscopy and intensity-modulated photovoltage spectroscopy, respectively. [36] We tackle this problem by carrying out intensity-modulated photocurrent spectroscopy (IMPS) measurements at open-circuit (OC) conditions on CH3NH3PbBr3 cells prepared by the flash infrared annealing method with different electron-selective contacts. [37] Indeed, intensity modulated photocurrent spectroscopy (IMPS) confirmed that hematite {012} surfaces exhibit higher rate constants for both charge transfer and recombination. [38] Meanwhile, intensity-modulated photocurrent spectroscopy and photoluminescence spectra demonstrate that rGO can promote the hot electrons transfer from Ag nanoparticles to Ti substrate, reducing the photogenerated electron–hole recombination. [39] Here, we address this knowledge gap and employ modulated photocurrent spectroscopy (MPC) to investigate localised states in the frequently studied amorphous phase of Ge2Sb2Te5.

Moreover, the combination of Fourier-transform photocurrent spectroscopy and electroluminescence external quantum efficiencies measurements demonstrated reduced non-radiative recombination energy loss upon the incorporation of PM6, resulting in a slightly enhanced open-circuit voltage of 0. [1] Combined with other characterization measurements, such as photoluminescence and Fourier transform photocurrent spectroscopy, these techniques demonstrate that air plays an important role in the passivation of the surface trap states of the perovskite films. [2] The defect healing ability of 1,10-phenanthroline is verified with a set of complementary techniques including photoluminescence (steady-state and time-resolved), space-charge-limited current (SCLC) measurements, light intensity dependent JV measurements, and Fourier-transform photocurrent spectroscopy (FTPS). [3] The use of this algorithm allowed us to get an excellent estimation of the valence band tail slope, as compared to the one obtained from measurements of the absorption coefficient by Fourier transform photocurrent spectroscopy and transmittance/reflectance. [4] Moreover, the effects of illumination on the absorption properties were investigated via Fourier Transform Photocurrent Spectroscopy, a technique that allows to access to weak absorptions (E.
