Synthesis, characterization and photovoltaic applications of a low band gap polymer based on s-tetrazine and dithienosilole.
A new copolymer of dithienosilole (DTS) and dithienyl-s-tetrazine (TTz), PDTSTTz, has been designed and synthesized. This solution processable polymer shows a low band gap, strong absorption and good thermal stability. Solar cells from the blend of this polymer with PC(71)BM showed power conversion efficiency (PCE) up to 4.2%.
