开发了一种简单的基于蒸汽的钙钛矿太阳能电池制造工艺，并将其应用于倒置平面 CH3NH3PbI3 (MAPbI3) 钙钛矿太阳能电池的制造。在此过程中，PbI2 薄膜通过真空蒸发沉积在空穴传输层 (HTL) 上，然后通过在甲基碘化铵 (MAI) 蒸气中退火将其转化为 MAPbI3 相。利用转换后的MAPbI3薄膜，我们通过气相工艺制备了倒置平面钙钛矿太阳能电池，器件结构为玻璃/TCO/HTL/MAPbI3/C60/BCP/Ag，其中PEDOT:PSS和铜酞菁（CuPc）用作HTL。使用CuPc作为HTL的太阳能电池通过完全气相工艺获得了高达16.1%的功率转换效率。此外，我们观察到使用 CuPc 代替 PEDOT:PSS 作为 HTL 时太阳能电池的稳定性得到改善。
A simple vapor-based fabrication process for perovskite solar cells is developed and applied to the fabrication of inverted planar CH3NH3PbI3 (MAPbI3) perovskite solar cells. In this process, PbI2 film is deposited by vacuum evaporation on the hole transport layer (HTL), followed by converting it into the MAPbI3 phase by annealing in methylammonium iodide (MAI) vapor. Using the converted MAPbI3 films, we fabricated inverted planar perovskite solar cells by vapor phase-based process with a device structure of glass/TCO/HTL/MAPbI3/C60/BCP/Ag, in which PEDOT:PSS and copper phthalocyanine (CuPc) were used as an HTL. A power conversion efficiency as high as 16.1% was obtained for the solar cell using CuPc as an HTL by a fully vapor-based process. Furthermore, we observed the improvement of the stability of the solar cells when using CuPc instead of PEDOT:PSS as an HTL.
