In situ ethanolamine ZnO nanoparticle passivation for perovskite interface stability and highly efficient solar cells
Sánchez-Godoy, H. E.; muhammed, kunnummal; Rodríguez-Rojas, Rubén; Zarazúa, Isaac; Masi, Sofia MDPI (2022-02-28)Zinc oxide (ZnO) has interesting optoelectronic properties, but suffers from chemical instability when in contact with perovskite interfaces; hence, the perovskite deposited on the top degrades promptly. Surface passivation ... -
Light-Induced Space-Charge Accumulation Zone as Photovoltaic Mechanism in Perovskite Solar Cells
Zarazúa, Isaac; Bisquert, Juan; Garcia-Belmonte, Germà American Chemical Society (2016)We fabricated formamidinium lead iodide perovskite solar cell for analysis of the photovoltaic mechanism based on the interpretation of the capacitance variation under illumination. It was shown that the low-frequency ... -
Noncapacitive hysteresis in perovskite solar cells at room temperature
Almora Rodríguez, Osbel; Aranda Alonso, Clara; Zarazúa, Isaac; Guerrero, Antonio; Garcia-Belmonte, Germà American Chemical Society (2016)The current density−voltage (J−V) curves of perovskite solar cells have been found to present a hysteresis-like distortion when the measurement is done by sweeping the applied voltage at different scan conditions. ... -
Preferred Growth Direction by PbS Nanoplatelets Preserves Perovskite Infrared Light Harvesting for Stable, Reproducible, and Efficient Solar Cells
Ansisar Erazo, Eider; Sánchez-Godoy, H. E.; Erazo, Eider A.; Gualdrón Reyes, Andrés Fabián; Khan, Ali Hossain; Agouram, Said; Barea, Eva M; Zarazúa, Isaac; Ortiz, Pablo; Cortés, María Teresa; Muñoz-Sanjosé, Vicente; Moreels, Iwan; Masi, Sofia; Mora-Sero, Ivan Wiley (2020)Formamidinium‐based perovskite solar cells (PSCs) present the maximum theoretical efficiency of the lead perovskite family. However, formamidinium perovskite exhibits significant degradation in air. The surface chemistry ...
