摘要: 本文探索在空气中制备高效率ZnO纳米纤维:P3HT:PCBM杂化太阳能电池的方法（简称ZnO:P3HT:PCBM电池），通过调控ZnO纳米纤维的纺丝时间，制备了效率达到2.94%的ZnO:P3HT:PCBM杂化太阳能电池。系统研究了纳米纤维的制备时间对电池光电性能的影响，采用扫描电镜（SEM）、电化学阻抗分析研究了ZnO纳米纤维的微观形貌及电池中的载流子传导特性。

Abstract: High performance bulk heterojunction solar cells based on ZnO nanofiberous networks:poly(3-hexylthiophene) (P3HT):6,6-phenylb C61-butyric acid methyl ester (PCBM) have fabricated in ambient air. The device with power conversion efficiency (PCE) of 2.94% has been fabricated. We studied systematically the effect of ZnO nanofibers’ electrospinning time on the characteristics of devices. The ZnO nanofiberous networks and the carrier transfer process of device are characterized by scanning electron microscopy (SEM) and electrochemical impedance spectroscopy (EIS) measurements.
