Influence of D/A ratio on photovoltaic performance of a highly efficient polymer solar cell system

Adv Mater. 2012 Dec 18;24(48):6536-41. doi: 10.1002/adma.201202719. Epub 2012 Oct 9.

Abstract

A new copolymer PIDTDTQx based on indacenodithiophene and quinoxaline is synthesized and characterized. The correlation between the D/A ratio, mobility, and photovoltaic properties, as well as morphology of the D/A blend based on a PIDTDTQx:PC(70) BM system is investigated. The power conversion efficiency of the polymer solar cells based on PIDTDTQx/PC(70) BM (1:4, w/w) reaches 7.51%.
