概要
- 論文の詳細を見る
Polythiophene derivatives with carboxylic acid groups directly attached to the thiophene rings were synthesized for polymer-sensitized solar cells (PSSCs). The polymer layer densely and uniformly covering the surface of the TiO2 particle in the photoanode of the PSSCs allows excitons to diffuse to the polymer/TiO2 interface efficiently. The PSSCs yielded a maximum incident photon-to-current conversion efficiency of about 80% at 480 nm and the open-circuit voltage (V_{\text{OC}}) values but also short-circuit current density (J_{\text{SC}}) values increased with decreasing hydrolysis ratio of the polymer.
