钙钛矿太阳能电池及其制备方法
摘要：
一种钙钛矿太阳能电池，其特征在于依次包括导电玻璃层、致密二氧化钛膜、多孔二氧化钛膜、掺杂CH3NH3Pb1‑xSb2x/3I3多晶膜、空穴传输材料层及蒸镀银电极层，所述的掺杂CH3NH3Pb1‑xSb2x/3I3多晶膜中高价态元素Sb取代CH3NH3PbI3中的Pb元素形成n型掺杂的CH3NH3Pb1‑xSb2x/3I3杂化材料，本发明还公开了钙钛矿太阳能电池的制备方法。与现有技术相比，具有光电转换效率高的优点。
摘要（英）：

A perovskite solar cell is disclosed. The perovskite solar cell is characterized by comprising a conductive glass layer, a compact titanium dioxide film, a porous titanium dioxide film, a CH3NH3Pb1-xSb2x/3I3 doped polycrystal film, a hole transport material layer and an evaporation silver electrode layer, wherein the high-valence-state element Sb in the CH3NH3Pb1-xSb2x/3I3 doped polycrystal film is adopted to replace a Pb element in CH3NH3PbI3 to form an n type CH3NH3Pb1-xSb2x/3I3 doped hybrid material. The invention also discloses a preparation method for the perovskite solar cell. Compared with the prior art, the perovskite solar cell has the advantage of high photoelectric conversion efficiency.
