Abstract

Various kinds of modifying methods towards ZnO and TiO2 one-dimensional nanostructures such as nanorods and nanotubes have been carried out for their applications in Dye-sensitized solar cell (DSSC), perovskite solar cell (PSC) and photo detectors (PD). Core-sheath ZnO/CdTe and double-sheath ZnO/CdSe/CdTe nanocable arrays as effective photoanode have been developed for solar cells, which resulted in a saturated current as high as 14.3 mA/cm2. Large area free-standing highly ordered TiO2 nanotube arrays on the fluorine-doped tin oxide (FTO) conductive glass substrates have been successfully obtained to serve as photo-anodes of DSSCs. The certified photovolatic conversioncy of TiO2 nanoarrays based DSSCs is up to 10.3% by using N719 as Dye and I-/I3- as electrolyte. Perovskite solar cell with efficiency of up to 18.6% based on TiO2 nanorod arrays is also presented. Self-powered broadband photodetectors based on CH3NH3PbI3/ZnO nanorod arrays heterostructure have been achieved with high detectivity of 3.56 × 1014 cm Hz1/2 W-1 and high responsivity of 24.3 A W−1.
