Perovskite/silicon tandem photovoltaics have attracted enormous attention in science and technology over recent years. In order to improve the performance and stability of the technology, new materials and processes need to be investigated. However, the established sequential layer deposition methods severely limit the choice of materials and accessible device architectures. In response, a novel lamination process that increases the degree of freedom in processing the top perovskite solar cell (PSC) is proposed. The very first prototypes of laminated monolithic perovskite/silicon tandem solar cells with stable power output efficiencies of up to 20.0% are presented. Moreover, laminated single-junction PSCs are on par with standard sequential layer deposition processed devices in the same architecture. The numerous advantages of the lamination process are highlighted, in particular the opportunities to engineer the perovskite morphology, which leads to a reduction of non-radiative recombination losses and and an enhancement in open-circuit voltage (V_oc). Laminated PSCs exhibit improved stability by retaining their initial efficiency after 1-year aging and show good thermal stability under prolonged illumination at 80 °C. This lamination approach enables the research of new architectures for perovskite-based photovoltaics and paves a new route for processing monolithic tandem solar cells even with a scalable lamination process.

叠层单片钙钛矿/硅串联光伏

近年来，钙钛矿/硅串联光伏在科技界引起了极大的关注。为了提高技术的性能和稳定性，需要研究新的材料和工艺。然而，已建立的顺序层沉积方法严重限制了材料的选择和可访问的器件架构。作为回应，提出了一种新的层压工艺，可提高顶部钙钛矿太阳能电池 (PSC) 的加工自由度。首次展示了具有高达 20.0% 的稳定功率输出效率的叠层单片钙钛矿/硅串联太阳能电池原型。此外，层压单结 PSC 与相同架构中的标准顺序层沉积处理设备相当。V_{或 c} )。层压 PSC 通过在 1 年老化后保持其初始效率而表现出更高的稳定性，并在 80 ° C 的长时间光照下表现出良好的热稳定性。这种层压方法能够研究基于钙钛矿的光伏电池的新架构，并为处理单片电池铺平了新途径即使采用可扩展的层压工艺，串联太阳能电池也是如此。
