제목 Synthesis and Characterizations of New Low Bandgap Polymer included Cyclopentadithiophene for OPVs
초록 These days, Many low bandgap polymers for solar cells were synthesized. P3HT and PCPDTBT were successful OPVs. New type for OPVs is D-A polymers which have two absorption band in UV-vis absorption spectra. These UV absorption bands can cover large area of solar spectrum. Recently, derivatives of PCPDTBT were synthesized and reported high photovoltaic properties. We designed and synthesized new acceptor material for D-A polymers. Novel conjugated polymer PCPDTMBI based on CPDT(cyclopentadithiophene) was synthesized by Stile coupling. The number molecular weight (Mn) of PCPDTMBI was 8.5 kg/mol, and the polydispersity index (PDI) was 2.1. UV-vis spectra of PCPDTMBI showed two band. Two λmax were 430 nm and 730 nm. Eopt was about 1.30 eV. The Power conversion effciciency is about 0.1%.
