In recent years, the performance of lead halide perovskite solar cells has increased dramatically, setting a record efficiency of 22.1%; however, their sensitivity towards water limits their utility and still needs to be addressed.
In this paper, oleylammonium polysulfides molecules were self-assembled on an etched perovskite film, leading to an enhancement in moisture stability of the devices.
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...
