| 摘 要： | 利用微波对基于poly(3-hexylthiophene) (P3HT)和 -phenyl-C61-buytyric acid methyl ester (PCBM) 的体异质结太阳能电池进行退火处理,提高了器件的效率。使用的微波频率为2.45 GHz,当处理时间为10 min时,获得的短路电流为9.13 mA/cm2,开路电压为0.63 V,能量转化效率为3.21%,其性能参数完全可以与普通真空干燥箱退火相比拟。研究了微波对活性层的作用,从微波退火处理后的UV-Vis吸收谱和SEM图发现,微波退火主要改善了活性层的粗糙度,提高了相分离程度,有利于激子在界面处的解离和载流子的传输。

| Abstract: | Microwave was applied to improve the efficiency of polymer solar cell based on poly(3-hexylthiophene)(P3HT) and -phenyl-C61-buytyric acid methyl ester(PCBM) bulk-heterojunction solar cells.With microwave radiation(2.45 GHz) for 10 min,short circuit current of 9.13 mA/cm2,open circuit voltage of 0.63 V,and energy conversion efficiency of 3.21% were obtained,similar or surpass to those of devices annealed with a hot plate for 20 min at 150 ℃.We examined the effect of microwave on the active layer.From the Uv-Vis absorption spectrum and the SEM image after microwave,we found that more rough morphology and larger phase separation occurred,which benefit for dissociation of exciton and transportation of carrier. |
