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 ...

Spray-coating perovskite PV devices over curved substrates

Conventional PV cells based on the ubiquitous semiconductor crystalline-silicon most often come in the form of flat, rigid and relatively heavy panels. Despite the fact that PV devices can be manufactured on flexible substrates, methods to integrate PV devices over ...
