Abstract
Glass/F:SnO2/CdS/CuO/Ag hetero structure has been fabricated using direct current (d.c) magnetron sputtering and thermal evaporation technique. Cupric oxide (CuO) has been synthesized by direct current magnetron sputtering technique and Cadmium sulphide (CdS) has been deposited by thermal evaporation method. The micro-structural and optical studies were carried out by field emission scanning electron microscope, transmission electron microscope, atomic force microscope and UV–vis spectroscopy. The above heterojunction structure shows the efficiency ∼2.1%. Open-circuit voltage of the cells was ∼0.462 V. The efficiency values obtained here are the highest compared to those reported so far for this glass/F:SnO2/CdS/CuO/Ag structure. Sputtering acted as a viable and inexpensive technique for obtaining this glass/F:SnO2/CdS/CuO/Ag cell structure for PV application.
