Construction of Solar Cells Using Organic Dyes

Abstract

This work is mainly based on the fabrication and characterization of Dye Sensitized Solar Cell (DSSC) using organic dyes and to compare its efficiencies. DSSCs were made with glass plates coated with Titanium dioxide, Tartaric acid, dish washing liquid which is non -toxic and more efficient. Glass plates were coated with TiO2, dishwashing liquid and Tartaric acid mixture as different blocks or cells and were dried for 24 hrs. Organic dye was prepared from beet root, henna, opuntia stincta, lawsone inermics extract. The as prepared dyes were coated on the TiO2 coating and it is dried. Aluminium foil and copperwire were used as working electrodes and were mounted on each cell. The cells were connected in series. This is completely covered with another glass plate and it was clipped. The cell was kept on the terrace to have the optimum sunlight and its output voltages were measured and efficiencies were calculated and compared.
