基于有机金属三卤化物钙钛矿光吸收剂的太阳能电池最近已经成为最有前途的光伏器件类别之一。考虑到它们的高性能，沿着它们的低制造成本，这样的装置对于建筑物集成光致发光器件是有吸引力的，特别是如果使其透明并用作太阳能窗。在这项研究中，开发了在可见光谱中具有高透明度的高效钙钛矿太阳能电池。这些器件包括具有高透明度和导电性的电介质-金属-电介质多层顶部电极，以及优化的基于溶液的薄且连续的甲基铵碘化铅膜。通过这种工艺和器件结构开发的组合，已经制备了具有高可见光透射率和创纪录的功率转换效率的半透明太阳能电池，包括具有低至55 nm的钙钛矿厚度的器件。(C)2015爱思唯尔有限公司版权所有。
Solar cells based on organometal trihalide perovskite light absorbers have recently emerged as one of the most promising class of photovoltaic devices. Given their high performances, along with their low fabrication costs, such devices are appealing for building integrated photovoltaics, especially if made semitransparent and used as solar windows. In this study, efficient perovskite solar cells with high transparency in the visible spectrum have been developed. These devices comprise a dielectric-metal-dielectric multilayered top electrode with high transparency and conductivity, and an optimized solution-based thin and continuous methylammonium lead iodide film. Through this combination of processing and device architecture developments, semitransparent solar cells with high visible transmittance and record power conversion efficiency have been prepared, including devices with a perovskite thickness as low as 55 nm.
