Outline of Final Research Achievements |
To realize solution-processed organic thin-film solar cells with low economical and environmental costs, the author has studied solution-processed organic solar cells using unmodified fullerene and halogen-free solvent. It has been found that the PTB7-Th:C70 photocells prepared with 1,2,4-trimethylbenzene show power conversion efficiency (PCE) of 5% under1 sun illumination. In comparison with the device with C70-PCBM, the device with unmodified C70 shows low PCE but superior thermal robustness. It has been also found that power conversion efficiency (PCE) becomes higher at lower light illumination.
