Abstract
A bithiazole unit-containing polymer has the following structural formula: wherein R1 is an alkyl group of C1-C20, R2 is an alkyl group of C1-C20, and n is an integer of 10-50. Carbazole is introduced to the structure of the bithiazole unit-containing polymer, and carbazole is an excellent hole transport unit, therefore the introduction of carbazole to the polymer can make the hole mobility of the polymer to be increased. An acceptor structure is formed between the carbazole unit and the bithiazole unit to form a donor-acceptor structure so that the band gap of the polymer is narrowed, and the absorption spectrum produces red shift to preferably match the solar spectrum. Connecting an alkyl chain to the thiophene can help to increase the solubility of the copolymer. The invention also provides a preparation method of the bithiazole unit-containing polymer and a solar battery device using the bithiazole unit-containing polymer. Application of the thiazothiazole unit-containing polymer in solar batteries can greatly improve the energy conversion efficiency.
