  Heteroatomic hole transport materials are provided. The hole transport materials include a non-carbon core: two, four, or eight aromatic groups covalently bound to the non-carbon core; a. terminal substituted diphenylamine end unit on each aromatic group: and optionally aromatic linker groups linking the aromatic groups and the substituted diphenylamine end units. In some embodiments the non-carbon core is non-carbon central atom such as Si, Ge, B − , P + Sn or Pb. In other embodiments, the non-carbon core is a cubic silsesquioxane. Also provided are methods for making these materials. The materials are particularly useful as hole transport materials in perovskite solar cells.

  提供了非碳核心的异原子孔传输材料。这些孔传输材料包括一个非碳核心：与非碳核心共价结合的两个、四个或八个芳香基团；每个芳香基团上的末端取代的二苯胺末端单元；以及可选的芳香连接基团，连接芳香基团和取代的二苯胺末端单元。在一些实施例中，非碳核心是非碳中心原子，如Si、Ge、B−、P+、Sn或Pb。在其他实施例中，非碳核心是立方体硅氧烷。还提供了制备这些材料的方法。这些材料在钙钛矿太阳能电池中作为孔传输材料特别有用。
