In recent years, the study of organic-inorganic halide perovskite as an optoelectronics material has been a significant line of research, and the power conversion efficiency of solar cells based on these materials has reached 25.5%. However, defects on the surface of the film are still a problem to be solved, and oxygen plasma is one of the ways to passivate surface defects. In order to avoid destroying the methylammonium lead iodide (MAPbI), the influence of plasma powers on film was investigated and the cesium triiodide (CsPbI) quantum dots (QDs) were doped into the film. In addition, it was found that oxygen plasma can enhance the mobility and carrier concentration of the MAPbI film.
近年来，有机-无机卤化物钙钛矿作为光电子材料的研究一直是一个重要的研究方向，基于这些材料的太阳能电池的功率转换效率已达到25.5%。然而，薄膜表面的缺陷仍然是一个有待解决的问题，氧等离子体是钝化表面缺陷的方法之一。为了避免破坏甲基碘化铅（MAPbI），研究了等离子体功率对薄膜的影响，并将三碘化铯（CsPbI）量子点（QDs）掺杂到薄膜中。此外，还发现氧等离子体可以提高MAPbI薄膜的迁移率和载流子浓度。
