摘要

半透明的有机太阳能电池适合作为发电元件集成到建筑物，汽车和温室等各种环境中。对于这些应用，一个重要的优点是光利用效率-定义为对可见光的透明度和功率转换效率的乘积。在这两个参数之间有一个权衡：具有强可见光吸收的材料（特别是电子供体聚合物）提供更高的功率转换效率。这种权衡使得提高光的利用效率具有挑战性。现在，苏州大学和中国科学院的陈海洋、朱娟、李耀文及其同事通过对电子给体聚合物的堆叠行为进行工程改造，提高了电荷传输效率，减少了可见光吸收，从而实现了超过6%的光利用效率。研究人员引入了一种添加剂，可以与电子供体聚合物形成氢键，抑制其聚集，有利于首尾滑动（或j型）堆叠结构。这种堆叠方式的特点是分子间共轭长度更长，既减少了可见光的吸收（提高了透明度），又有利于电荷的传输（提高了功率转换效率）。此外，添加剂提高了电子受体分子的结晶度，增加了其对近红外光的吸收，进一步提高了功率转换效率。通过加入光干涉层，研究团队实现了13.31%的功率转换效率和45.23%的平均可见光透过率，从而实现了6.02%的光利用效率。为了解决实际可行性，研究人员探索了他们的方法与大面积太阳能模块的兼容性，并进行了初步的植物生长实验。
