The Analysis of Pyrostegia Venusta Flower Mediated Dye as Sensitizer for TiO2 Based Dye Sensitized Solar Cells

Abstract

Since no vacuum systems or expensive equipment are needed in their fabrication, dye sensitized solar cells (DSSCs) are anticipated to be one of the effective solar cells of third generation delivering green energy at low production costs. The structure and operating principles of the dye-sensitized solar cell (DSSC) are reviewed in this work. Optical characterization and extraction of detail is provided on pyrostegia venusta. The preparation steps, dye-based optical and electrical characterization of the DSSC, are all covered. The sensitized solar cell having maximum conversion efficiency(1.99%)is capable of producing an open circuit voltage Voc (1.94V) and a short circuit current isc (1.804mA) when exposed to solar irradiation.
