Dye-sensitized solar cells with an energy storage function are demonstrated by modifying its counter electrode with a poly (vinylidene fluoride)/ZnO nanowire array composite. This simplex device could still function as an ordinary solar cell with a steady photocurrent output even after being fully charged. An energy storage density of 2.14 C g(-1) is achieved, while simultaneously a 3.70% photo-to-electric conversion efficiency is maintained.
具有储能功能的染料敏化太阳能电池通过修饰其对电极的聚偏二氟乙烯/氧化锌纳米线阵列复合材料来实现。这种简单的器件在完全充电后仍然可以作为普通太阳能电池,具有稳定的光电流输出。实现了 2.14 C g(-1) 的能量存储密度,同时保持了 3.70%的光电转换效率。
