Synthesis of a Phenothiazine-Quinoxaline Polymer for Photovoltaic Applications

摘要

Polymer solar cells (PSCs) have attracted considerable attention because of their unique advantages of low cost, light weight, and potential use in flexible devices. Based on the concept of a bulk heterojunction (BHJ) structure, PSCs made by blending poly(3-hexylthiophene) (P3HT) as a p-type material and [6,6]-phenyl-C61-butyric acid methyl ester (PC6iBM) as an n-type material have been most intensively investigated and have shown power conversion efficiencies (PCEs) up to 5-6%.
