有效的光捕获方案是通过补偿光吸收不足来提高薄膜光伏（PV）电池功率转换效率（PCE）的关键。为了无缝处理从纳米级到微米级的光学元件，本研究精心设计了多尺度光学模拟，用于定性分析微透镜阵列（MLA）、V形结构和新提出的方案（根据太阳每日和每年的运动称为双抛物线捕获器（DPT））的光捕获性能。通过完美捕获两个抛物面光伏电池之间的入射光，DPT 有潜力显着提高基于 PCDTBT:PC70BM 的聚合物太阳能电池的 PCE，从 5.9% 提高到 8.9%。 (c) 2013 年美国光学学会
An efficient light trapping scheme is a key to enhancing the power conversion efficiency (PCE) of thin-film photovoltaic (PV) cells by compensating for the insufficient light absorption. To handle optical components from nano-scale to micro-scale seamlessly, a multi-scale optical simulation is carefully designed in this study and is used to qualitatively analyze the light trapping performances of a micro lens array (MLA), a V-shaped configuration, and the newly proposed scheme, which is termed a double parabolic trapper (DPT) according to both daily and annual movement of the sun. DPT has the potential to enhance the PCE significantly, from 5.9% to 8.9%, for PCDTBT:PC70BM-based polymer solar cells by perfectly trapping the incident light between two parabolic PV cells.
