| Abstract | Abstract Two new acceptor-donor-acceptor small molecules DINDTS and DINCNDTS, with dithienosilole as a core unit and 1,3-indanedione (IN) or malononitrile derivative 1,3-indanedione (INCN) units as end-capped groups, respectively, have been designed and synthesized for solution-processable bulk-heterojunction (BHJ) solar cells. The impact of these two end-capped groups on their optical, electrochemical properties and photovoltaic performance was systematically studied. The optimal DINDTS:PC 71 BM based solar cells showed a short-circuit current density ( J sc ) of 13.50 mA cm −2 and power conversion efficiency (PCE) of 6.60%. However, DINCNDTS:PC 71 BM based devices exhibited a poor PCE of 0.58% with a very low J sc of 1.82 mA cm −2 , which are mainly due to its poor morphology of active layers. |
