This work demonstrated a-Si:H thin-film solar cells with backside TiO(2) / SiO(2) distributed Bragg reflectors (DBRs) for applications involving building-integrated photovoltaics (BIPVs). Selectively transparent solar cells are formed by adjusting the positions of the DBR stop bands to allow the transmission of certain parts of light through the solar cells. Measurement and simulation results indicate that the transmission of blue light (430 ~500 nm) with the combination of three DBR mirrors has the highest increase in conversion efficiency.
这项工作展示了用于建筑一体化光伏（BIPV）应用的带有背面TiO(2)/SiO(2)分布布拉格反射器（DBR）的非晶硅氢化薄膜太阳能电池。通过调整DBR阻带的位置来形成选择性透明太阳能电池，以允许特定部分的光透过太阳能电池。测量和模拟结果表明，结合三个DBR镜时蓝光（430~500nm）的透过率能使转换效率得到最高提升。
