摘要

Randomly oriented ZnO microsheets were successfully self-assembled on TiO2 nanoparticle(TN) film to act as the scattering layer via a cathodic electrodeposition process.The light scattering properties of ZnO microsheets were studied by UV-Vis spectrometer in the 400-800 nm wavelength range.It was found that ZnO microsheets exhibited excellent ability to scatter the incident light for ZnO microsheet-TiO2 nanoparticle(ZT) composite films.The results showed that dye-sensitized solar cells(DSSCs) fabricated with ZT composite films showed higher short-circuit density(Jsc) and conversion efficiency than TN-based DSSCs,due to the light scattering properties of ZnO microsheets.
