Wavelength-Dependent Photoluminescence Mapping of Depth-Dependent Degradation Under Thermal Stress in Phenethylammonium Tetrafluoroborate Treated Perovskite Solar Cells
Julisa Juarez, Akash Dasgupta, Alan Zhan +2
Studying real-time degradation in perovskite semiconductors remains an important challenge. Conventional methods often cannot separate interfacial and bulk processes or rely on des…
Disentangling the origin of degradation in perovskite solar cells via optical imaging and Bayesian inference
Akash Dasgupta, Robert D. J. Oliver, Manuel Kober-Czerny +5
Machine learning and computational inference, coupled with experimental data, promise to significantly accelerate our rate of learning in most scientific disciplines. In this study…
Degradation Dynamics of Perovskite Solar Cells Under Fixed Reverse Current Injection
Fangyuan Jiang, Haruka Koizumi, Hannah Contreras +8
Previous studies of reverse-bias stability in perovskite solar cells have focused primarily on voltage controlled reverse-bias tests. Here we instead present an investigation of pe…
Deriving a comprehensive dataset of optical constants for metal halide perovskites
Akash Dasgupta, Shuaifeng Hu, Seongrok Seo +5
Accurate optical constants are essential for modelling light propagation, absorption, and ultimately photovoltaic performance in state of the art perovskite solar cells and is espe…
