Abstract
AbstractWe designed and synthesized two new zinc porphyrin dyes for dye‐sensitized solar cells (DSCs). Subtle molecular structural variation in the dyes significantly influenced the performance of the DSC devices. By utilizing these dyes in combination with a cobalt‐based redox electrolyte using a photoanode made of mesoporous TiO2, we achieved a power conversion efficiency (PCE) of up to 12.0 % under AM 1.5 G (100 mW cm−2) simulated solar light. Moreover, we obtained a high PCE of 6.4 % for solid‐state dye‐sensitized solar cells by using 2,2′,7,7′‐tetrakis‐(N,N‐di‐p‐methoxyphenylamine)‐9,9′‐spirobifluorene as a hole‐transporting material.
