纳米结构的半导体金属氧化物，特别是基于纳米纤维的光电极可以在染料敏化太阳能电池（DSSC）中提供增强的能量转换效率。在这项研究中，ZnO/聚（醋酸乙烯酯）复合材料的预浸料直接静电纺丝到玻璃基板上涂有F：SnO 2，然后热压在120 ℃和450 ℃煅烧。这导致由具有30 nm单个晶粒的200 - 500 nm直径核的扭曲结构组成的多个纳米颗粒网络。使用ZnO纳米纤维垫的DSSC在100 mW/cm（2）（AM- 1.5G）照明下表现出1.34%的转换效率。(C)2007年，美国物理学会。
Nanostructured semiconducting metal oxides and particularly nanofiber-based photoelectrodes can provide enhanced energy conversion efficiencies in dye-sensitized solar cells (DSSCs). In this study ZnO/poly (vinyl acetate) composite nanofiber mats were directly electrospun onto a glass substrate coated with F:SnO2, then hot pressed at 120 degrees C and calcined at 450 degrees C. This resulted in multiple nanofiber networks composed of a twisted structure of 200 - 500 nm diameter cores with 30 nm single grains. The DSSCs using ZnO nanofiber mats exhibited a conversion efficiency of 1.34% under 100 mW/cm(2) (AM- 1.5G) illumination. (C) 2007 American Institute of Physics.
