Analysis of the Origin of Open Circuit Voltage in Dye Solar Cells
American Chemical Society (2012)Changes in the composition of the electrolyte are known to affect the parameters that determine the performance of dye solar cells. This paper describes a robust method for the analysis of the photovoltage in dye solar ... -
Classification of solar cells according to mechanisms of charge separation and charge collection
Royal Society of Chemistry (2015)In the last decade, photovoltaics (PV) has experienced an important transformation. Traditional solar cells formed by compact semiconductor layers have been joined by new kinds of cells that are constituted by a complex ... -
Co-adsorbing effect of bile acids containing bulky amide groups at 3β-position on the photovoltaic performance in dye-sensitized solar cells
Elsevier (2019)Co-adsorbing molecules attain certain control in the surrounding of the dyes leading to enhanced efficiencies mainly by affecting the recombination of the photogenerated electrons and aggregation of dyes. Bile acids such ... -
Intensity-Modulated Photocurrent Spectroscopy and Its Application to Perovskite Solar Cells
American Chemical Society (2020-09-23)Frequency domain techniques are useful tools to characterize processes occurring on different time scales in solar cells and solar fuel devices. Intensity-modulated photocurrent spectroscopy (IMPS) is one such technique ... -
Negative Capacitance and Inverted Hysteresis: Matching Features in Perovskite Solar Cells
American Chemical Society (2020-10-01)Negative capacitance in the low-frequency domain and inverted hysteresis are familiar features in perovskite solar cells, which origin is still under discussion. Here we use impedance spectroscopy to analyze these responses ...
