Transient Photovoltage Measurements on Perovskite Solar Cells with Varied Defect Concentrations and Inhomogeneous Recombination Rates

Wolfgang Richard Tress, Zaiwei Wang, Brian Irving Carlsen, Firouzeh Ebadi Garjan

In all kinds of solar cells, transient photovoltage (TPV) decay measurements have been used to determine charge carrier lifetimes and to quantify recombination processes and orders. However, in particular, for thin-film devices with a high capacitance, the ...

Tailored Amphiphilic Molecular Mitigators for Stable Perovskite Solar Cells with 23.5% Efficiency

Shaik Mohammed Zakeeruddin, Felix Thomas Eickemeyer, Yuhang Liu, Ulf Anders Hagfeldt, Mohammad Ibrahim Dar, Xiong Li, Dan Ren, Zaiwei Wang, Bowen Yang, Linfeng Pan, Brian Irving Carlsen, Hongwei Zhu, Marco Alejandro Ruiz Preciado, Shilong Wang, Xiaofei Dong

Passivation of interfacial defects serves as an effective means to realize highly efficient and stable perovskite solar cells (PSCs). However, most molecular modulators currently used to mitigate such defects form poorly conductive aggregates at the perovs ...
