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 ... -
Low-temperature processed electron collection layers of graphene/TiO 2 nanocomposites in thin film perovskite solar cells
Wang, Jacob Tse-Wei; Ball, James M.; Barea, Eva M; Abate, Antonio; Alexander-Webber, Jack A.; Huang, Jian; Saliba, Michael; Mora-Sero, Ivan; Bisquert, Juan; Snaith, Henry J.; Nicholas, Robin J. American Chemical Society (2014)The highest efficiencies in solution-processable perovskite-based solar cells have been achieved using an electron collection layer that requires sintering at 500 °C. This is unfavorable for low-cost production, applications ... -
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 ... -
Observation of Long-Term Stable Response in MAPbBr3 Single Crystals Monitored through Displacement Currents under Varying Illumination
García-Batlle, Marisé; Zia, Waqas; Aranda Alonso, Clara; Saliba, Michael; Almora Rodríguez, Osbel; Guerrero, Antonio; Garcia-Belmonte, Germà Wiley-VCH GmbH (2022-06-30)Long life of perovskite devices in working conditions remains the bottleneck for technology application. Stable charge carriers’ transport together with nonreactive contact materials contributes to the increase of the ...
