Study of the Efficiency of polymer Solar Cells Fabricated from Natural Dyes and Chemical Dyes

Abstract

The Solar cells are fabricated from (fluoride Tyne oxide (FTO) glass / polymer /dye / Copper) was used in each cell of a different types of dyes, natural dye (Chrolorpheel – Helba) and chemical dye (Ecerchrom – Dry Ink). And studied the efficiency and fill factor for all samples produced also studied the relationship between intensity of ligh and efficiency of the cell and found that the intensity of ligh does not affect efficiency of the cell. Also, for these samples it’s found that the efficiency of cell using Ecerchrom is 6%, fill factor is 0.95. The efficiency of cell using Dray Ink is 11%, fill factor is 0.87. And the efficiency of cell using Chrolorpheel is 19%, fill factor is 0.90. And the efficiency of cell using Helba is 14%, fill factor is 0.88. The efficiency and fill factor were different with use different types of dyes. It also found that natural dyes (Chrolorpheel – Helba) has more voltage and efficiency than chemical dyes (Ecerchrom – Dry Ink ).
