摘要

钙钛矿材料在过去十年中引起了越来越多的兴趣。钙钛矿太阳能电池(PSC)效率的迅速提高,加上与溶液加工和薄膜技术的兼容性,使其成为光伏研究的焦点。最重要的是,通过成分变化的带隙可调性使它们成为串联应用的完美候选者,允许进一步收集太阳辐射光谱并提高功率转换效率(PCE)。为了将所有这些优势转化为大规模生产,并在能源生产市场上增加传播,钙钛矿制造必须适应和优化使用高通量,连续工艺,如超声波喷涂(USSC)。在本文中,我们研究了用于光伏应用的超声喷涂钙钛矿层,特别关注了淬火辅助结晶步骤。介绍了不同的淬火工艺,并在最终层形貌和电池性能方面进行了比较。最后,气淬与大规模相容沉积一起使用,并允许生产PCE >15%的钙钛矿太阳能电池。

A study of quenching approaches to optimize ultrasonic spray coated perovskite layers scalable for PV
Perovskite materials have gathered increased interest over the last decade. Their rapidly rising efficiency, coupled with the compatibility with solution processing and thin film technology has put perovskite solar cells (PSC) on the spotlight of photovoltaic research. On top of that, band gap tunability via composition changes makes them a perfect candidate for tandem applications, allowing for further harvest of the solar irradiation spectrum and improved power conversion efficiency (PCE). In order to convert all these advantages into large scale production and have increased dissemination in the energy generation market, perovskite fabrication must be adapted and optimized with the use of high throughput, continuous processes, such as ultrasonic spray coating (USSC). In this paper we investigate the ultrasonically spray coated perovskite layers for photovoltaic applications, with particular focus on the quenching-assisted crystallization step. Different quenching techniques are introduced to the process and compared in terms of final layer morphology and cell performance. Finally, gas quenching is used with the large-scale-compatible deposition and allows the production of perovskite solar cells with PCE >15%.
