Description
Summary:The development of an artificial photosynthetic system is a promising strategy to convert solar energy into chemical fuels. Herein, we report the facile synthesis of WO 3 /CdS heterostructures as high-performance photoanodes for dye sensitized solar cells (DSSCs). The ability of the composite to produce current after the removal of incident light was linked to the trapping of photo excited electrons by the WO 3 portion. Further it was analyzed using XPS, PL, and UV–Vis diffuse reflectance spectroscopy characterization techniques. SEM and TEM results suggest that individual spherical shaped nanoparticles sizes in the range of 20–25 nm was uniformly decorated on the outer surface of WO 3 nanotubes. The photo-conversion efficiency of 9.95% was obtained with the configuration WO 3 /CdS (100 mg) that represent a 2.5-fold increment compared to bare WO 3 (4.21%) as well as commercial Pt (5.01%). The experimental results are discussed in detail. CdS could significantly improve the light absorption ability in the visible light region and rapid production of charge carriers in the WO 3 photoanode. This study could also provide a new train of thought on designing of heterostructure photoanode with photovoltaic properties, promoting the applications of solar energy.
