Characterization of Crosslinked Organic Photovoltaic Devices |
| 초록 |
The performance of thin-film organic photovoltaic cells based on polymer blended with [6,6]-phenyl-C60-butyric acid methyl ester (PCBM) has been strongly related to morphology of active layer. Major factors influencing morphology of polymer/PCBM blend are the composition ratio and conditions of thermal treatment. However, at the solar cell operation temperature, PCBM can diffuse into host polymer causing further phase separation and leading decrease in power conversion efficiency. To solve this problem, we are focused on the stability of the devices. [6,6]-phenyl-C60-butyric acid 3-ethylthiophene ester has been electrochemically copolymerized with 3-octylthiophene so that crosslinked PCBM unit is connected to the conducting polymer matrix. In this structure, PCBM can not move around even at the elevated temperature. The effect of anchoring PCBM unit is possible to explain the thermal stability of the devices. |
