Polyselenopheno[3,4-b]selenophene for Highly Efficient Bulk Heterojunction Solar Cells

Herein we describe the synthesis of a new series of copolymers (PSeBx) containing selenopheno[3,4-b]selenophene and benzodiselenophene, which exhibited a high power conversion efficiency (PCE) of 6.87% in a bulk heterojunction (BHJ) solar cell device (PSeB2/PC71BM). In comparison with its thiophene...

Description
Summary:Herein we describe the synthesis of a new series of copolymers (PSeBx) containing selenopheno[3,4-b]selenophene and benzodiselenophene, which exhibited a high power conversion efficiency (PCE) of 6.87% in a bulk heterojunction (BHJ) solar cell device (PSeB2/PC71BM). In comparison with its thiophene analogue, PTB9, the new polyselenopheno[3,4-b]selenophene-co-benzodiselenophene (PSeB2) showed a lower band gap and improved charge carrier mobility as high as 1.35 × 10–3 cm2 V–1 s–1.
