采用溶剂热法在导电玻璃衬底上制备了支化ZnO纳米线，用于染料敏化太阳能电池（dsc）。在使用纳米颗粒时，一维支链纳米结构可以提供直接的传导途径，而不是粒子间的跳跃。分支ZnO纳米线dsc的短路电流密度和能量转换效率分别为4.27 mA/cm(2)和1.51%，是裸ZnO纳米线dsc的2倍。这种改进是光电极内表面积扩大的结果，使我们能够实现更高的染料吸附，从而显着提高dsc的性能。
Branched ZnO nanowires have been fabricated on conductive glass substrates via a solvothermal method for dye-sensitized solar cells (DSCs). The 1D branched nanostructures can afford a direct conduction pathway instead of interparticle hops while using nanoparticles. Furthermore, the short-circuit current density and the energy conversion efficiency of the branched ZnO nanowire DSCs are 4.27 mA/cm(2) and 1.51%,which are twice as high as the bare ZnO nanowire ones. The improvement was a consequence of the enlargement of the internal surface area within the photoelectrode and allowed us to achieve higher dye adsorption to significantly enhance the performance of the DSCs.
