摘要:

在过去的十年间,钙钛矿太阳能电池(PSCs)的功率转换效率(PCE)已从最初的3.8%提升至26.1%,可与硅基太阳能电池相媲美。目前,PSCs已经成为最具商业化应用前景的新型光伏技术。高效大面积钙钛矿模组的制备是实现其商业化应用的必经之路。目前,实验室中小面积(≤1cm2)的高性能PSCs一般通过旋涂法制备。在这种方法中,溶剂的快速蒸发可以实现均匀的钙钛矿薄膜。而在制备钙钛矿太阳能模组(PSMs)时,旋涂法则会造成基底中心与外侧之间的薄膜厚度不均匀、溶液浪费及处理窗口期较短等问题,因此旋涂法并不适用于制备大面积的PSMs (>10cm2)。为了解决上述问题,近年来研究人员相继开发了各种制备工艺,包括刮刀涂布法、狭缝涂布法、喷涂法、丝网印刷及气相沉积等方法。本文主要综述了近年来PSMs的薄膜制备工艺,并针对各种溶剂及添加剂对器件效率及稳定性的影响进行了讨论。

Abstract:

In the past decade, the power conversion efficiency(PCE) of perovskite solar cells(PSCs) has been improved from the initial 3.8% to certified 26.1%, which is close to the value achieved by silicon-based solar cells. So far, PSCs have become the most promising newgeneration photovoltaic technology for commercial application. The development of highlyefficient and large area perovskite module is the way to realize its commercial application.Currently, high performance PSCs at the laboratory scale(≤1cm2) are generally prepared by the spin-coating method. In this process, the rapid evaporation of solvent can achieve uniform perovskite films on small area devices. However, in the preparation of perovskite solar modules(PSMs), the spin-coating method will cause problems such as uneven thickness of the film between the center and outsider of the substrate, solution waste, and short processing window,which has certain drawbacks for the fabrication of commercial PSMs with a large area(>10cm2). To solve these problems, different preparation technologies have been developed in recent years, including blade coating, slot-die coating, spray coating, screen printing and vapor deposition, etc. In this review, we mainly focus on the development of preparation process of PSMs with large-area, and further discuss the effects of various solvents and additives on the PCEs and stability of the PSMs.
