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 50 %.
