UV- and NIR-blocking properties of ZnO/ATO bilayer films prepared by RF magnetron sputtering

Films with ultraviolet (UV) and near-infrared (NIR) blocking properties can be used to protect against UV and heat radiation, thus prolonging the operating life of photovoltaic devices. Being wide band-gap semiconductors, ZnO films can absorb UV light and antimony doped tin oxide (ATO) films can play the role of defending against the NIR light with low electrical resistivities. In this work, the bilayer films of ZnO overlayed by ATO are...
