Novel photosensitized dyes having trifluoromethylacrylic acid as an acceptor-anchor moiety (MCL26–29) are synthesized. These dyes seem to suppress the back-donation currents from the conduction band of TiO2 semiconductor to the electrolyte. Their fabricated dye-sensitized solar cells (DSCs) show high IPCE performances (MCL27; over 80% between 400–520 nm, max 90% at 465 nm). In particular, the high IPCE properties are compared with more than 80 article examples.
合成了具有三氟甲基丙烯酸作为接受体-锚定基团的新型光敏染料(MCL26–29)。这些染料似乎抑制了TiO2半导体导带向电解质的反向给电子电流。它们制造的染料敏化太阳能电池(DSCs)展现了高的光电流转换效率(IPCE)性能(MCL27;在400–520 nm之间超过80%,在465 nm时达到最高90%)。特别是,这些高IPCE特性与超过80篇文献实例进行了比较。
