The Effect of Cyano Substituent on Nano-Scale Morphology of Bulk Heterojunction Solar Cells |
| 초록 |
The morphological and photovoltaic characteristics of naphthalene-based conjugated polymers:PC71BM blends are studied with and without cyano substituted group as an electron deficient group on a conjugated polymer. PBTADN:PC71BM blend solar cells exhibited an extended optical absorption over the solar spectrum and homogeneous nano-scale morphology that enhanced charge carrier transport compared to PBTDN:PC71BM which does not possess cyano substituent. Without annealing processing, the bulk-heterojunction devices of PBTADN:PC71BM blend yielded an open circuit voltage (VOC) of 0.89 V, a current density (JSC) values of 7.4 mA/cm2, a fill factor (FF) of 0.51, and power conversion efficiency (PCE) values of 3.4 %, showing highly increased VOC and FF with respect to PBTDN:PC71BM blend solar cells. This study suggests that the conjugated polymer including cyano substituted group has distinct advantages for the development of highly efficient polymer solar cells. |
