To dye for: Two new dyes are synthesized by structural modifications of one of the best dyes for NiO p‐type dye‐sensitized solar cells, which is based on a triphenylamine–dicyanovinyl donor–acceptor system. An additional thiophene unit near the anchoring group can greatly retard charge recombination while enhancing the absorption coefficient to significantly improve the photoconversion efficiency by
用于染色:通过对NiO p型染料敏化太阳能电池的最佳染料之一进行结构修饰,合成了两种新染料,该染料基于三苯胺-双氰基乙烯基供体-受体体系。锚定基团附近的另一个噻吩单元可以大大延迟电荷重组,同时提高吸收系数,从而将光转换效率显着提高50%。
