Transparent solar cells maximize installation space by being applicable to glass areas such as building windows and sunroofs, necessitating high power conversion efficiency (PCE), long-term stability, and aesthetic appeal. This study demonstrates the development of transparent crystalline silicon (c-Si) solar cells that exhibit vivid colors, enhanced PCE, and long-term stability. To achieve vivid coloration, a metal-oxide-based color filter with a single metal layer and TiO thin films, which show high transmittance, is integrated into the neutral-colored transparent c-Si solar cells. As a result, the proposed all-inorganic-based transparent solar cells exhibited red, green, and blue colors, achieved a high PCE of 15.3%, and demonstrated long-term stability for up to 1000 h by leveraging c-Si solar cells in conjunction with all inorganic color filters.
透明太阳能电池可应用于建筑窗户和天窗等玻璃区域，从而最大限度地利用安装空间，这就要求具备高功率转换效率（PCE）、长期稳定性和美观性。本研究展示了一种透明晶体硅（c-Si）太阳能电池的开发成果，该电池呈现出鲜艳的色彩、更高的PCE以及长期稳定性。为实现鲜艳的色彩，一种具有单一金属层的金属氧化物基滤色器和具有高透射率的TiO薄膜被集成到中性色透明c-Si太阳能电池中。结果，所提出的全无机基透明太阳能电池呈现出红色、绿色和蓝色，实现了15.3%的高PCE，并通过将c-Si太阳能电池与全无机滤色器结合使用，展示了长达1000小时的长期稳定性。
