Abstract

Two narrow bandgap copolymers derived from 6,6′,12,12′- tetraoctyl-indeno[1,2-b]fluorene and bithiophene or thieno[3,2-b]thiophene-cored benzothiadiazole are synthesized and characterized. The copolymers show broad absorption in the range 350-700 nm. The application of the copolymers as photovoltaic cells with configurations ITO/PEDOT:PSS/blend/Al and ITO/PEDOT:PSS/blend/interlayer/Al is investigated. A power conversion efficiency (PCE) of approximately 3.0% is achieved under an AM 1.5G solar simulator (80 mW cm^-2) for the cells with ITO/PEDOT:PSS/polymer:PC ₇₁BM([6,6]-phenyl-C₇₁ butyric acid methyl ester) (1:4)/interlayer/Al. Two narrow bandgap alternating copolymers derived from 6,6′,12,12′-tetraoctylindeno[1,2-b]fluorene and bithiophene or thieno[3,2-b]thiophene-cored benzothiadiazole, named PIF-DDBT and PIF-DTBT, are synthesized and characterized. The application of the copolymers for PVCs, with device configurations ITO/PEDOT:PSS/blend/Al and ITO/PEDOT:PSS/blend/interlayer/ Al, is investigated.
