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.

钙钛矿太阳能电池一个简单的基于气相制造工艺开发和应用，以反转平面CH的制造₃ NH ₃碘化铅₃（MAPbI ₃）的钙钛矿太阳能电池。在此过程中，通过真空蒸发将PbI ₂膜沉积在空穴传输层（HTL）上，然后通过在甲基碘化碘（MAI）蒸气中退火将其转化为MAPbI ₃相。使用转换后的MAPbI ₃薄膜，我们通过基于气相的工艺制造了倒置平面钙钛矿太阳能电池，其器件结构为玻璃/ TCO / HTL / MAPbI ₃ / C ₆₀/ BCP / Ag，其中PEDOT：PSS和铜酞菁（CuPc）被用作HTL。使用CuPc作为HTL的太阳能电池通过完全基于蒸汽的工艺获得了高达16.1％的功率转换效率。此外，当使用CuPc代替PEDOT：PSS作为HTL时，我们观察到了太阳能电池稳定性的提高。
