Solar cells (photovoltaic cells) represent a promising solution as an environmental benign system converting solar energy (sun light) to electricity. Key challenges in the industrial-scale application of solar cells are to improve the solar-to-electric conversion efficiency and to reduce the cost of materials and fabrication processes. The solution is to develop low-cost and high-efficiency materials and optimize the fabrication processes. Owing to its small band gap value and low cost, Nickel Tungstate (NiWO4) nanomaterials are promising candidates for application in solar cells. In this project, nanoscale particles of NiWO4 will be prepared using different chemical approaches. Prepared nanomaterials will be characterized with different techniques, such as TEM, atomic force microscopy (AFM), XRD, UV-Vis. Solar cell modules/devices will be fabricated and their photoelectrical properties will be studied. The overall solar cell efficiency of each compound will be studied using photo-electrochemical techniques in the presence and absence of light. Then, NiWO4-nanoparticles will be doped with different metal ions to understand the effect of doping on bandgap and light conversion. The overall solar cell efficiency of each compound will be studied using photo-electrochemical techniques in the presence and absence of light. Further, we will also explore how surfactants will affect the morphology and their properties of doped metal oxide semiconductor nanomaterials.
