Cadmium Doped with Selenides and Telluride for Photovoltaic Applications: A Review

Abstract: Materials are the heart and soul of photovoltaic devices. Based on the nature of materials, photovoltaics (solar cells) have been classified into various types. Based on its classifications many oxide and metallic materials are mainly used for photovoltaic applications. Device structure and nature of materials are very critical for the overall efficiency and performance of photovoltaics. However here in this particular review we will be only converging on the nature of various materials used to develop solar cells and their performances by using the materials of C, Cd, In doped Selenides and Telluride. Likewise the use of nanomaterials for biosensors based in thin film, particularly carbon based materials and its doping with selenides and telluride have attracted considerable attention due to provide a high surface-volume ratio, faster electron transfer and label-free responses. This review discussed these materials and its efficiencies.

Performance of Solar cell fabricated using TiO2: rGO on glass and Si substrates prepared by Thermal Evaporation Technique

Abstract: TiO2: rGO doped material is deposited on glass and Si substrates. These hetero nanostructures have multiple applications in photovoltaic because of their charge transport properties. In this study, we prepared tetragonal TiO2: rGO doped material is deposited on glass and Si substrates (NCs) using Thermal Evaporation method. The morphological properties of the NCs were investigated using X-ray diffraction, Field-emission scanning electron microscopy with EDAX analysis, Atomic force microscopy, and Photovoltaic studies analysis. The results showed that the surface area of the deposited films increased significantly and the anatase TiO2: rGO doped material is deposited on glass and Si substrates was efficient photovoltaic performance with the other nanocomposites or the bare individual nanoparticles. It may be attributed to the increased active surface area, the increased adsorption of the light and target surface atoms, as well as efficient electron–hole transformation.
