Electron transporting materials based on ternary metal oxides (TMOs) with graphene incorporation are the best electron transport layers (ETLs) for perovskite solar cells (PSCs).
Controlling the grain size of the organic–inorganic perovskite thin films using thiourea additives now crossing 2 μm size with >20% power conversion efficiency.
Defects, inevitably produced in the solution-processed halide perovskite films, can act as charge carrier recombination centers to induce severe energy loss in perovskite solar cells (PSCs). Suppressing these trap states...
Much effort has been made to push the power conversion efficiency of perovskite solar cells (PSCs) towards the theoretical limit. Recent studies have shown that post deposition treatment of barrier...
