Machine-Learning Force Fields Reveal Shallow Electronic States on Dynamic Halide Perovskite Surfaces
Previous studies indicated that defects in halide perovskites can generate shallow electronic states, which are crucial for their performance in devices. However, how shallow states persist amid prono...

Why are halide perovskites so efficient? Part of their great performance is in their nature of electronic surface states. ☀️
In our preprint, we reveal the atomistic origins of benign surface states using machine-learning force fields 🤖.

Suppressing Halide Segregation in Wide‐Bandgap Perovskite Absorbers by Transamination of Formamidinium
All-perovskite tandem solar cells are emerging at a fast rate because of their potential to exceed efficiencies of Si-perovskite tandems, in combination with faster manufacturing, lower cost and the ....
