Abstract

Semitransparent organic photovoltaics (ST-OPVs) have gained significant attention due to their rapid iteration of high-efficiency photoactive materials and potential applications in building-integrated photovoltaics as smart windows. In this work, we establish a parameter (FoM_LUE) to evaluate the potential of photoactive materials for ST-OPVs, combining average visual transmittance, bandgap, and current density. PBOF and eC9 exhibit the highest FoM_LUE values of 0.084 and 0.161 for the investigated donors and acceptors, respectively. We achieve a light utilization efficiency of 6.05% as the figure of merit for all semitransparent solar cells. The derived ST-OPV exhibits enhanced thermal insulation and operational stability compared to its counterpart. The geographical analysis indicates that the hot summer/warm winter zone is the most suitable for ST-OPV glazing windows, delivering an annual total energy-saving of 1.43 GJ m^-2. Our results demonstrate the multifunctionality and geographical factors of ST-OPVs for constructing sustainable energy-saving smart windows.

具有广泛地理适应性的半透明有机光伏电池作为可持续智能窗户

半透明有机光伏（ST-OPVs）由于其高效光活性材料的快速迭代和在建筑集成光伏系统中作为智能窗户的潜在应用而受到了极大的关注。在这项工作中，我们建立了一个参数（FoMLUE）来评估st - opv光活性材料的潜力，结合平均视觉透过率，带隙和电流密度。供体和受体的PBOF和eC9分别表现出0.084和0.161的最高FoMLUE值。我们实现了6.05%的光利用效率作为所有半透明太阳能电池的优点数字。与同类产品相比，衍生的ST-OPV具有增强的绝热性和操作稳定性。地理分析表明，夏热冬暖地区最适合ST-OPV玻璃窗，年总节能1.43 GJ m-2。我们的研究结果展示了st - opv用于构建可持续节能智能窗户的多功能性和地理因素。
