Zinc oxide (ZnO) thin film is grown on glass substrate by the sol-gel spin coating technique. The prepared film annealed at 450 °C. X-ray diffraction shows that the ZnO Film is polycrystalline with (002) preferential orientation. We have found the Surface roughness was minimum (12.4 nm) by atomic force microscopy. The optical band gap is found to be 3.12±0.01 eV by UV-visible Spectroscopy. The Wave...
Light trapping in the thin film solar cell has been studied for a while and is considered as among the most important parameter which may reduce the gap between the most efficient single junction thin film solar cell available till date and the theoretical Shockley-Queisser (SQ) Limit. Usually, metallic back reflectors are being used for the thin film solar cells. Here we are presenting an alternative...
