Kinetic Suppression of Photoinduced Halide Migration in Wide Bandgap Perovskites via Surface Passivation
Farhad Akrami, Fangyuan Jiang, Rajiv Giridharagopal +1
In this work, we study the kinetics of photoinduced halide migration in FACsPb(IBr) wide (~1.69 eV) bandgap perovskites and show halide migratio…
Dimethylammonium additives alter both vertical and lateral composition in halide perovskite semiconductors
Sarthak Jariwala, Rishi Kumar, Giles E. Eperon +3
Adding a large A-site cation, such as dimethylammonium (DMA), to the perovskite growth solution has been shown to improve performance and long-term operational stability of halide…
Approaching the limits of optoelectronic performance in mixed cation mixed halide perovskites by controlling surface recombination
Sarthak Jariwala, Sven Burke, Sean Dunfield +7
We demonstrate the critical role of surface recombination in mixed-cation, mixed-halide perovskite, FA0.83Cs0.17Pb(I0.85Br0.15)3. By passivating non-radiative defects with the poly…
Sn4+ Precursor Enables 12.4% Efficient Kesterite Solar Cell from DMSO Solution with Open Circuit Voltage Deficit Below 0.30 V
Yuancai Gong, Yifan Zhang, Erin Jedlicka +12
The limiting factor preventing kesterite (CZTSSe) thin film solar cell performance further improvement is the large open-circuit voltage deficit (Voc,def) issue, which is 0.345V fo…
