Provided herein are dyes, dye-sensitized solar cells, and sequential series multijunction dye-sensitized solar cell devices. The dyes include an electron deficient acceptor moiety, a medium electron density ?-bridge moiety, and an electron rich donor moiety comprising a biaryl, a substituted biaryl, or an R1, R2, R3 substituted phenyl where each of R1, R2, and R3 independently comprises H, aryl, multiaryl, alkyl substituted aryl, alkoxy substituted aryl, alkyl substituted multiaryl, alkoxy substituted multiaryl, OR4, N(R5)2, or a combination thereof; each R4 independently comprises H, alkyl, aryl, alkyl substituted aryl, alkoxy substituted aryl, or a combination thereof; and each R5 independently comprises aryl, multiaryl, alkyl substituted aryl, alkoxy substituted aryl, alkyl substituted multiaryl, alkoxy substituted multiaryl, or a combination thereof. The solar cells include a glass substrate, a dye-sensitized active layer, and a redox shuttle. The devices include at least two dye-sensitized solar cells connected in series.
本文提供了染料、染料敏化太阳能电池以及顺序串联多结构染料敏化太阳能电池器件。这些染料包括一个电子亏欠的受体基团,一个中等电子密度的?-桥基团,以及一个富电子的供体基团,包括一个联苯、一个取代联苯,或一个R1、R2、R3取代苯基,其中R1、R2和R3中的每一个独立地包括H、芳基、多芳基、烷基取代的芳基、烷氧基取代的芳基、烷基取代的多芳基、烷氧基取代的多芳基、OR4、N(R5)2或它们的组合;每个R4独立地包括H、烷基、芳基、烷基取代的芳基、烷氧基取代的芳基或它们的组合;每个R5独立地包括芳基、多芳基、烷基取代的芳基、烷氧基取代的芳基、烷基取代的多芳基、烷氧基取代的多芳基或它们的组合。太阳能电池包括玻璃基板、染料敏化活性层和氧化还原穿梭体。该器件包括至少两个串联连接的染料敏化太阳能电池。
