摘要

通过刮涂制备薄膜衬底和真空蒸镀有机小分子材料来构筑复合界面传输层，制备了大面积有机太阳能电池模组器件。通过透射光谱、传输层粗糙度形貌、表面浸润性、不同衬底的光吸收层粗糙度形貌、刮涂的均匀性研究了同传输层对OSCs器件性能的影响。实验结果表明，当在AZO衬底表面蒸镀一层电子致密层时，即新型复合传输层并未影响基片在300~900 nm范围内的透过率，并且BPhen电子致密层可以有效地提高基片表面的平整度和浸润性，这也有利于后续光吸收层溶液的刮涂，提高涂膜的质量和稳定性。通过不同基底刮涂光吸收层薄膜表面粗糙度以及形貌图，其新型复合传输层作为衬底刮涂出的光吸收层薄膜的表面粗糙度有了明显的降低，表明平整的基底有利于刮涂出表面均一的薄膜。由此制备的基于新型复合传输层的刚性、柔性模组器件的开路电压（

）、短路电流密度（

）和填充因子（FF）都有大幅度的提高。最终制备的新型刚性模组器件光电转化效率（PCE）提高到10.62%，提升了约13%;柔性模组器件的光电转化效率（PCE）达到5.13%，提升了32%。

Abstract

Based on a new composite interface transport layer

large-area organic solar cell module was fabricated by vacuum evaporation of organic small molecular materials. According to the transmittance spectrum

surface roughness morphology and surface wettability of transport layer

the surface roughness of active layers based on different substrates

the uniformity of blade coating and the influence of different transport layers on the performance of organic solar cells were analyzed. The experimental results show that when the electronic dense layer of 4

7-diphenyl-1

10-phenanthroline(BPhen) acetylimide is deposited on the surface of aluminum-doped zinc oxide substrate

the new composite transport layer is formed

which does not affect the light transmittance of the substrate in the range of 300-900 nm. In addition

the electron dense layer of BPhen can effectively improve the flatness and wettability of the substrate surface

which is beneficial to the subsequent scraping of the active layer solution and improves the quality and the stability of the coating film. By analyzing the surface roughness and three-dimensional morphology of the active layer film coated on different substrates

the surface roughness of the active layer film coated on the AZO(Al doped ZnO)/BPhen new composite transport layer was significantly reduced. It means that the new composite transport layer as substrate is beneficial to scrape out a uniform active layer film. As a result

the open circuit voltage(

)

short-circuit current density(

) and fill factor(FF) of rigid and flexible module device are significantly improved

and the power conversion efficiency(PCE) of the new rigid modular device is increased to 10.62%

which is about 13% higher than stand device. Importantly

the PCE of the flexible module device reaches 5.13%

which is also approximately 32% higher than AZO-based device.
