摘要：

The pressure is introduced as a parameter in the post-treat process for perovskite solar cells. Via a hot-pressing method, the rough surface of perovskite film becomes smooth, and the pin-holes can be cured. This modified perovskite morphology can help to improve charge transporting and eliminate recombination in the perovskite solar cells. Moreover, significantly enhanced photovoltaic performances with high PCEs of 10.84% and 16.07% are thus achieved in HTM-free type and spiro-OMeTAD based cells, respectively.
