Adjusting the Energy Bands of WO<sub>3</sub>@ZnO Nanocomposite Heterojunction Through the Combination of WO<sub>3</sub> Thin Film to Improve its Photoelectric Performance
At present, nanomaterials with high-quality photoelectric properties are urgently needed to be used in the manufacture of solar cells. In this study, the hydrothermal synthesis method was first used to grow ZnO nanorod arrays, and then a layer of WO<sub>3</sub> thin film with controllabl...

| description |
At present, nanomaterials with high-quality photoelectric properties are urgently needed to be used in the manufacture of solar cells. In this study, the hydrothermal synthesis method was first used to grow ZnO nanorod arrays, and then a layer of WO<sub>3</sub> thin film with controllable thickness was prepared on ZnO nanorod arrays by magnetron sputtering, forming a series of WO<sub>3</sub>@ZnO nanocomposite heterojunction. We found that the value of the photocurrent of the prepared nanocomposite samples is nearly 30 times higher than WO<sub>3</sub> films under illumination, and it is more stable. The results show that this controllable microstructure can further modify the surface properties of ZnO nanorods, and possess the high visible absorption and photoelectric conversion efficiency. By controlling the thickness of the WO<sub>3</sub> film, the band can be regulated and ultimately optimized the photoelectrochemical properties of the composite structure. |
