By intelligently utilizing the odd-even effect existing in the melting points of alkanes as presented in the basic textbook of Organic Chemistry, different alkoxy groups were introduced to modify the structure of commercial Spiro-OMeTAD to give new Spiro derivatives of Spiro-OEtTAD, Spiro-OPrTAD, Spiro-OiPrTAD and Spiro-OBuTAD, with the aim to adjust the molecular packing status in perovskite solar cells as hole transporting compounds. Excitedly, with the introduction of ethoxy groups instead of the methoxy ones in Spiro-OMeTAD, Spiro-OEtTAD-based perovskite solar cells demonstrated the highest device performance of 20.16%, higher than that of Spiro-OMeTAD (18.64%).
HETEROATOMIC-BASED HOLE-TRANSPORT MATERIALS
-
Paragraph 0013, (2021/04/30)
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.

Paragraph 0135-0137, (2016/10/08)
The present invention relates to a hole-transporting compound having a novel structure and, more specifically, to a hole-transporting compound for an inorganic/organic hybrid perovskite-based solar cell. In the present invention, the inorganic/organic hybrid perovskite-based solar cell including a hole-transporting body has very high generating efficiency.(AA) Hole transferring layer(BB) Inorganic/organic perovskite layer(CC) TiO_2 layer(DD) Transparent conductive film(FTO)COPYRIGHT KIPO 2016
