摘要

以聚3-己基噻吩（P3HT）和富勒烯衍生物（PCBM）体系的有机太阳能电池器件为基础，采用喷涂法制备了有机太阳能电池的空穴传输层和有机功能层，研究了基底温度对薄膜的形貌和器件性能的影响，并采用喷涂技术制备了一面积为11.2 cm

的大面积有机太阳能电池器件。研究发现，随着基底温度的升高，薄膜的粗糙度下降，吸收率提高，当基底温度为130 ℃时器件的性能最优，面积为25 mm

的器件的能量转换效率为2.09%。将多个独立的小面积电池进行串联和并联，制备了有效面积为11.2 cm

的大面积有机太阳能电池组件，其能量转换效率为1.83%，在面积增大44.8倍的情况下，效率仅损失不到13%。

Abstract

A heterojunction solar cell based on poly (hexylthiophene) (P3HT) and fullerene (PCBM) was fabricated. The hole transport layer and the active layer were prepared by spraying. The effect of the substrate temperature on the morphology of the active layer and the performance of the device were studied. The results show that the film roughness decreases and the absorption rate increases when the substrate temperature increases. And when the substrate temperature is 130 ℃

the device performance is optimized and the efficiency of a 25 mm

-size device is 2.09%.The small size devices were combined in series and parallel to achieve a 11.2 cm

-size large area organic solar array and the conversion efficiency is 1.83%. It is found that the area is increased by 44.8 times

while the efficiency loss is less than 13%.
