Topic: DYE SENSITIZED SOLAR CELLS

Description: Introduction: A low-cost and environmentally friendly alternative to conventional silicon based solar cell devices is the dye sensitized solar cells DSSCs . The first dye-sensitized solar cells DSSCs was presented by Michel Gr tzel at the Swiss Federal Institute of Technology. DSSC devices comprises of four major constituents: semiconductor electrode n-type TiO2 , dye sensitizer, redox electrolyte and counter electrode carbon or platinum .Objectives: The aim of this research is to extract dye from different plants and utilize them as photoactive layers in DSSCs. Expected results and Contribution to Knowledge: The findings from this research will contribute to the existing body of knowledge on DSSCs. By identifying the most effective plant extract, this research will improve the stability and conversion efficiency.

Stability of Polymer Based Perovskite Solar Cells

Introduction:Solar photovoltaics are the fastest-growing energy technology today, and a leading candidate for carbon-free electricity generation at the terawatt scale. Photovoltaic PV technology deployment is dominated by crystalline silicon wafer-based technologies, which benefit from high power conversion efficiencies, abundant materials, and proven manufacturability. Rapid declines in PV electricity costs approaching wholesale grid parity have been observed in many locations. The rapid rise in efficiency of thin-film solar cells using organometal halide perovskite semiconductors has made this class of photovoltaic device a highly promising technology for solar energy conversion. Currently, the PCE of perovskite cells is predominantly limited by charge transport and charge carrier recombination. Aim: Studying the environmental stability of polymer perovskite solar cells. Methodology: Utilizing the current fabrication methods of perovskite cells in order to change the physical properties of the absorber layer by changing its chemical composition. Expected result: at the end of the research, the effect of different fabrication methods on stability and PCE will be determined
