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...
Tandem solar cells (TSCs) are devices made of multiple junctions with complementary absorption ranges, which aim to overcome the Shockley–Queisser limit of single-junction solar cells. Currently, metal-halide hybrid perovskite solar...
