不含金属的有机染料在染料敏化太阳电池(DSC)中的应用愈加广泛,以芳胺为电子给体的D-π-A分子是其中重要的一类。本文依据芳香胺的结构,将近5年来应用于DSC中的100多个D-π-A分子分成4类,包括:基于N-烷基-苯胺的D-π-A光敏染料,基于三苯胺的D-π-A光敏染料,由包含芴基团的三芳胺构建的D-π-A光敏染料,包含芳胺基团的其他结构类型的D-π-A光敏染料。评述了它们的光电转换性能。
Metal-free organic photosensitizers are widely used in dye-sensitized solar cells (DSCs), of which D-π-A molecules with aromatic amine as electron donor (D) represent one of the most important types. On the basis of the structures of the aromatic amine moiety, more than 100 D-π-A type organic photosensitizers utilized in DSCs over the past five years are classified into 4 categories, including D-π-A dyes based on N-alkyl-aniline, D-π-A dyes based on triphenylamine, D-π-A dyes based on fluorene-containing triphenylamine, and other types of aromatic amine-containing D-π-A dyes, and their photoelectric conversion properties are reviewed.
