Discerning recombination mechanisms and ideality factors through impedance analysis of high-efficiency perovskite solar cells
Almora Rodríguez, Osbel; Taek Cho, Kyung; Aghazada, Sadig; Zimmermann, Iwan; Matt, Gebhard J.; Brabec, Christoph J.; Nazeeruddin, Mohammad Khaja; Garcia-Belmonte, Germà Elsevier (2018)The ubiquitous hysteresis in the current-voltage characteristic of perovskite solar cells (PSCs) interferes in a proper determination of the diode ideality factor (n), a key parameter commonly adopted to analyze recombination ... -
Ionic Dipolar Switching Hinders Charge Collection in Perovskite Solar Cells with Normal and Inverted Hysteresis
Almora Rodríguez, Osbel; López Varo, Pilar; Taek Cho, Kyung; Aghazada, Sadig; Meng, Wei; Hou, Yi; Echeverría-Arrondo, Carlos; Zimmermann, Iwan; Matt, Gebhard J.; Jiménez Tejada, Juan Antonio; Brabec, Christoph J.; Nazeeruddin, Mohammad Khaja; Garcia-Belmonte, Germà Elsevier (2019-06-15)Drift-diffusion modeling of the ionic dipole switching from the measurement of fast scanned and long pre-biased electrical response is proposed as a novel protocol for evaluation of limit hysteretic effects in perovskite ... -
Selective Growth of Layered Perovskites for Stable and Efficient Photovoltaics
Taek Cho, Kyung; Lee, Yonghui; Almora Rodríguez, Osbel; Grancini, Giulia; Ryu, Jaehoon; Tschumi, Manuel; Jang, Jyongsik; Paek, Sanghyun; Garcia-Belmonte, Germà; Nazeeruddin, Mohammad Khaja Royal Society of Chemistry (2018-11)Perovskite solar cells (PSCs) are promising alternatives toward clean energy because of their high-power conversion efficiency (PCE) and low materials and processing cost. However, their poor stability under operation ...
