Development of an organic solar cell using natural dyes for photovoltaic solar panels

This research endeavors to create and produce an organic solar cell employing natural dyes as photoactive materials. The study follows a systematic approach, comprising the identification of suitable dyes, construction, and testing of Grätzel-type cells, and evaluation of the electrical output in relation to the cell's composition. Subsequently, a comparative analysis is conducted to gauge the efficiency of the cell based on the type of natural dye employed. The resulting solar cells demonstrated voltage outputs ranging from 607 mV to 646 mV. The natural dyes are ranked in ascending order of voltage production, with beet juice yielding the lowest and Guinea sorrel yielding the highest output. Notably, the fabricated cells achieve their peak voltages after approximately fifty-two minutes of continuous solar irradiation, following one minute of exposure.
