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…
