Combining Modulated Techniques for the Analysis of Photosensitive Devices
Alvarez, Agustin; Ravishankar, Sandheep; Fabregat-Santiago, Francisco Wiley-VCH GmbH (2021-09-03)Small-perturbation techniques such as impedance spectroscopy (IS), inten-sity-modulated photocurrent spectroscopy (IMPS), and intensity-modulated photovoltage spectroscopy (IMVS) are useful tools to characterize and model ... -
Large grain size with reduced non-radiative recombination in potassium incorporated methylammonium-free perovskite solar cells
Anaya Gonzalez, Gabriela Stephania; Jeronimo-Rendon, Jose J.; WANG, QIONG; Li, Guixiang; Alvarez, Agustin; Fabregat-Santiago, Francisco; Köbler, Hans; alvarado, jose alberto; Juárez Santiesteban, Hector; Turren Cruz, Silver Hamill; Saliba, Michael; Abate, Antonio Elsevier (2022-12-31)Organic–inorganic hybrid halide perovskites are widely considered to be one the most promising material in photovoltaic technology, the use of this semiconductor as absorbent layer in solar cells has attracted considerable ... -
Negative Capacitance and Inverted Hysteresis: Matching Features in Perovskite Solar Cells
Alvarez, Agustin; Arcas, Ramón; Aranda Alonso, Clara; Bethencourt, Loengrid; Mas, Elena; Saliba, Michael; Fabregat-Santiago, Francisco 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 ... -
New Views on Carrier Diffusion and Recombination by Combining Small Perturbation Techniques: Application to BiVO4 Photoelectrodes
Alvarez, Agustin; García-Tecedor, Miguel; Montañés, Laura; Mas, Elena; Gimenez, Sixto; Fabregat-Santiago, Francisco Wiley (2022)Impedance spectroscopy (IS), intensity-modulated photocurrent spectroscopy (IMPS), and intensity-modulated photovoltage spectroscopy (IMVS) are well-established powerful modulated techniques to characterize optoelectronic ...
