A review on the fabrication techniques of large-area perovskite solar cells

近年来,钙钛矿太阳能电池因其制造成本低、生产技术相对简单、且具有良好的光电转换性能而受到广大研究者们的重视。大面积钙钛矿太阳能电池的产业化发展是提高太阳能源利用率、带动经济发展,应对气候变化的有效方式。但目前,高效率的钙钛矿太阳能电池均为实验室制备的小面积电池,不适用于大面积生产;因此,实现钙钛矿太阳能电池的产业化,就需要对大面积器件的制备技术方法进行探索和优化。本文聚焦于大面积钙钛矿太阳能电池制备方法,从3个方面展开:首先介绍了钙钛矿材料及太阳能电池结构,其次对大面积制备技术方法进行了介绍和比较,再次针对实现大面积高性能器件的一个关键技术钙钛矿油墨设计,开展了深入介绍和讨论。最后,本文对大面积钙钛矿太阳能电池制备方法存在的问题进行了讨论,并对未来发展进行了展望。

In recent years,perovskite solar cells have received significant attention from researchers due to their low cost,relatively simple production techniques and excellent photovoltaic conversion performance.The industrial development of large-area perovskite solar cells is an effective way to improve solar energy utilization,drive economic growth and address climate change.However,currently high-efficiency perovskite solar cells are mainly small-area devices prepared in laboratories,which are not suitable for large-scale production.Therefore,exploration and optimization of fabrication techniques for large-area devices are necessary to achieve industrialization of perovskite solar cells.This article focuses on the fabrication methods of large-area perovskite solar cells,covering three aspects.Firstly,the article introduces the perovskite material and the structure of perovskite solar cells.Secondly,it provides an introduction and comparison of fabrication techniques for large-area devices.Furthermore,a thorough introduction and discussion are carried out regarding the key technology of perovskite ink design for achieving high-performance large-area devices.Finally,the article discusses the problems associated with the fabrication methods of large-area perovskite solar cells and provides an outlook on future developments.
