与不透明光伏器件相比，透明光伏（TPV）器件具有许多独特的优点。然而，平衡效率和透明度一直很困难。迄今为止，当平均可见光透射率（AVT）超过70%时，PCE超过1%的TPV器件很少。在这里，我们报告了一系列的卤化铅的热塑性硫化弹性体，提高了效率和透明度。系统地研究了卤化铅层的厚度和成分的影响。随后，评价了卤化铅TPV的效率、透明度和稳定性。结果表明，具有紫外波长选择性吸收的卤化铅热塑性弹性体的热效率可达1%以上，而AVT可达70%以上。本研究提供了一种简单的方法来制备具有高效率和高可见光透明度的UV-收获TPV，其作为单结电池或作为多结透明和不透明电池的组分是潜在可行的。
Transparent photovoltaic (TPV) devices have a number of unique advantages compared with opaque photovoltaic devices. However, balancing efficiency and transparency has been difficult. To date, few TPV devices with PCE over 1% have been demonstrated when the average visible transmission (AVT) is over 70%. Here, we report a series of lead halide based TPVs with both increased efficiency and transparency. The effects of lead halide layer thickness and composition were systematically studied. Subsequently, the efficiency, transparency, and stability of lead halide TPVs were evaluated. Results show that lead halide TPVs with ultraviolet (UV) wavelength-selective absorption can achieve efficiencies over 1% while the AVT is above 70%. This study provides a simple approach to prepare UV-harvesting TPVs with high efficiency and high visible transparency that are potentially viable as single-junction cells or as a component of multijunction transparent and opaque cells.
