The semi-transparent solar cells are promising to be applied in building integrated photovoltaic (BIPV) and tandem solar cells. In this study, we fabricate semi-transparent and stable solar cells for BIPV by utilizing a poly (ethylene oxide) electrolyte and controlling the size of TiO nanoparticles and the thickness of the TiO film. The power conversion efficiency of the semi-transparent (over 50% transmittance at 620-750 nm) and quasi-solid solar cells is 5.78% under standard AM1.5G, 100 mW cm. The higher conductivity and smaller diffusion resistance of the quasi-solid electrolyte inside the mesoporous TiO film indicate the confinement effects of the polymer electrolyte inside a mesoporous TiO film. The unsealed semi-transparent and quasi-solid solar cell retains its initial efficiency during 1000 h irradiation in humid air.
半透明太阳能电池有望应用于建筑一体化光伏（BIPV）和串联太阳能电池。在本研究中，我们通过使用聚环氧乙烷电解质并控制TiO纳米颗粒的尺寸和TiO薄膜的厚度，制备了用于BIPV的半透明且稳定的太阳能电池。在标准AM1.5G、100 mW/cm²条件下，半透明（在620 - 750 nm处透过率超过50%）准固态太阳能电池的功率转换效率为5.78%。介孔TiO薄膜内部准固态电解质较高的电导率和较小的扩散电阻表明了聚合物电解质在介孔TiO薄膜内部的限域效应。未密封的半透明准固态太阳能电池在潮湿空气中1000小时的辐照过程中保持其初始效率。
