Alkoxysubstituted-MBI Containing Low Band Gap Polymers for High Performance Organic Photovoltaics |
| 초록 |
Main chain donor−acceptor (D−A) alternating design is a very efficient way to tune the absorption and energy level of conjugated polymers through the intramolecular charge transfer from donor to acceptor unit. In this work, we design and synthesize three D−A alternating copolymers with thiophene and bithiophene as the donor unit and 4,7-dibromo-5,6-dioctyloxy-2,2-dimethyl-2H-indene as the acceptor unit. The above result demonstrates that the absorption and electrochemical properties can be improved by fine-tuning the conjugated polymer structure. The best solar cell performance obtained has a layered structure of ITO / PEDOT:PSS / PTDOMBI:PC71BM(1:4) / Al. Under white light illumination (AM 1.5 G, 100 mW/cm2), the obtained Jsc is 4.03 mA/cm2, Voc is 0.58 V, FF is 32%, and PCE is 0.76%. Study to improve the solar cell architecture and PCE is underway. |
