STUDY OF DYE SENSITIZATION FOR SOLAR ENERGY CONVERSION INTO ELECTRICAL ENERGY IN TROPAEOLIN OO EDTA SYSTEM

Photogalvanic cells are electrochemical devices capable of solar power generation and storage. Tropaeolin OO is used as a photosensitizer in photogalvanic cell for solar energy conversion. EDTA was used as an electron donor. The system gave a photopotential of 860.0mV, photocurrent 340.0µA and power 150.68µW. The conversion efficiency and fill factor was determined as 1.44% and 0.51 respectively. The storage capacity of the cell was 80.0 minutes in dark
