Toxic substance usage remains one of the major concerns that must be addressed toward the commercialization of perovskite photovoltaics. Herein, we report a highly efficient perovskite solar module (>13%) fabricated via a wet process that uses a unique aqueous Pb(NO3)2 precursor, eliminating the use of toxic organic solvents during perovskite film preparation. In addition, we demonstrate a unique pattern in a monolithically interconnected module structure to check the uniformity of perovskite film and the quality of laser scribing. Finally, we highlight that this aqueous Pb(NO3)2 precursor protocol could achieve an enormous cost reduction over conventional PbI2 organic solutions whether in the laboratory research stage or at mass production scale, strengthening the core competitiveness of perovskite solar cells in the Darwinian ocean of photovoltaic technologies.
有毒物质的使用仍然是钙钛矿光伏商业化必须解决的主要问题之一。在此，我们报告了一种通过湿法工艺制造的高效钙钛矿太阳能模块（>13%），该工艺使用独特的硝酸铅水溶液前驱体，在钙钛矿薄膜制备过程中无需使用有毒有机溶剂。此外，我们展示了一种在单片互连模块结构中的独特图案，以检查钙钛矿薄膜的均匀性和激光划片的质量。最后，我们强调，无论在实验室研究阶段还是大规模生产规模，这种硝酸铅水溶液前驱体方案都可以比传统的碘化铅有机溶液大幅降低成本，从而在光伏技术的竞争环境中增强钙钛矿太阳能电池的核心竞争力。
