Fabrication of Next Generation Solar Cells - Chandrasekar P - Bog

Among various photovoltaic technologies, Dye-Sensitized Solar Cells (DSSCs) have gained attention as an efficient and commercially viable option. DSSCs belong to the third generation of solar cells and have become a prominent research area within solar photovoltaics. They are particularly appealing due to their simpler fabrication procedures and cost-effectiveness compared to Si-based solar cells. It is aimed to fabricate Dye Sensitized Solar cell using Screen Printing technique using N719 photosensitizer and CDCA as co-adsorbent. Then, the values of short circuit current density (Jsc), open circuit voltage (Voc), fill factor (FF), Power conversion efficiency (Pce) before and after degradation of 30 days duration are calculated. It is analysed for J-V plot and P-V plot using cyclic voltammetry analysis before and after degradation. Efforts to improve the efficiency of DSSCs focus on selecting dyes with higher adsorption coefficients and broader absorption wavelength ranges, enabling better utilization of solar energy.
