The performance of hybrid organic–inorganic perovskite solar cells has reached a certified efficiency of 25.5% over the past decade, which has attracted significant attention as a promising candidate for photovoltaic (PV) applications. However, the most efficient perovskite solar cells were produced by the technique of spin coating, which is extremely limited in terms of upscaling production for the commercialization of the technology. Furthermore, the efficiencies of large-area perovskite modules are still significantly lower than those of lab size solar cells. Thus, there are still some challenges that need to be overcome to bridge the efficiency gap between small-area perovskite solar cells and large-area perovskite devices. The first challenge lies in preparing high-quality perovskite layers by low-cost and scalable techniques with high reproducibility. Second, selecting and depositing charge extraction layers as well as bottom and top electrodes by scalable and low-cost techniques are essential tasks. In this review, recent progress and challenges of scalable technologies for solution-based coating and printing of perovskite PVs are summarized and analyzed. Based on the analysis, strategies and opportunities are proposed to promote the development of stable and efficient large-area perovskite PV toward commercialization.

升级溶液处理的钙钛矿光伏

在过去十年中，混合有机 - 无机钙钛矿太阳能电池的性能已达到 25.5% 的认证效率，作为光伏 (PV) 应用的有希望的候选者引起了极大的关注。然而，最高效的钙钛矿太阳能电池是通过旋涂技术生产的，这在该技术商业化的规模化生产方面极为有限。此外，大面积钙钛矿模块的效率仍明显低于实验室尺寸的太阳能电池。因此，要弥合小面积钙钛矿太阳能电池和大面积钙钛矿器件之间的效率差距，仍有一些挑战需要克服。第一个挑战在于通过低成本和可扩展且具有高重现性的技术制备高质量的钙钛矿层。其次，通过可扩展和低成本的技术选择和沉积电荷提取层以及底部和顶部电极是必不可少的任务。在这篇综述中，总结和分析了钙钛矿光伏溶液基涂层和印刷可扩展技术的最新进展和挑战。在此分析的基础上，提出了促进稳定高效的大面积钙钛矿光伏向商业化发展的策略和机遇。总结和分析了基于溶液的钙钛矿PVs涂层和印刷可扩展技术的最新进展和挑战。在此分析的基础上，提出了促进稳定高效的大面积钙钛矿光伏向商业化发展的策略和机遇。总结和分析了基于溶液的钙钛矿PVs涂层和印刷可扩展技术的最新进展和挑战。在此分析的基础上，提出了促进稳定高效的大面积钙钛矿光伏向商业化发展的策略和机遇。
