Excited State Processes in Perovskite Films and Nanostructures

Perovskite semiconductors show amazingly clean semiconductor behaviour for solution-processed materials, leading to highly efficient photovoltaics. However, their ultimate efficiency is limited to~28% by the same thermalisation losses that constrain any single-junction semiconductor, where energy above the bandgap is dissipated as ...
