Low-Band Gap Polymers Alternated with Donor-Acceptor Molecules Containing Carbazole Chains |
| 초록 |
Solar energy harvesting using the photovoltaic effect requires active semiconducting materials to convert light into electricity. Organic and polymeric solar cells have various merits such as flexibility, facile processing and manipulation, low weight, low cost for large area compliant devices. For the practical applications, there are serious limitations in present organic solar cells due to the relatively low mobility of charge carriers in the organic semiconductors and the narrow absorption bands. One of widely used approaches in order to solve these problems is developing push-pull polymers with alternating electron rich and electron poor units. Our group has been also pursuing to design and synthesize new low band-gap polymers based on diketopyrrolopyrrole (DPP) molecules with different donors for tuning their band-gaps and improving photovoltaic performance. Bulk-heterojunction solar cells using these polymers and PCBM gave a power conversion efficiency of 2~3 %. |
