ICENES'19 is an International Conference organized by Department of Physics, The Gandhigram Rural Institute Deemed to be University, Gandhigram is attracting researchers across the world working in the field of Solar Cells. Due to higher fabrication cost of crystalline Silicon solar cells with discouraging Power Conversion Efficiency (PCE), metal oxides, ternary oxides and perovskites in both crystalline and nano forms are being used to enhance PCE. Similarly, nanostructures of different morphologies like nanowire, nanotubes, chunk shaped nanostructures, dumbbell and flower type morphologies and core shell nanostructures are also tried. Since there is an increasing demand for the alternate energy resources particularly solar energy globally, an intense research on the fabrication of solar cells with enhanced Power Conversion Efficiency (PCE) has been going on for the past two decades.
