Production and characterization of organic dye-sensitive solar cell vi̇a tea

Increasing energy needs researches in recent years have led to a research tendency towards balanced, efficient and sustainable energy sources. This study was carried out in order to obtain a more efficient, balanced and sustainable energy source. In this study, organic dye sensitive solar cell structure was used. In the study, ITO glasses were coated with TiO2 and then annealed at certain times and at appropriate temperatures. The annealed coated films were left to rest. The edges of the coated films were cleaned with acetone and dried at 2400C for 15 minutes. 400 µl of brewed tea was dripped onto the ITO coated surface in appropriate proportions, and annealing was performed for 5 minutes. After annealing, 800 µl was added and annealed for 5 more minutes. In this study, a more stable battery structure was obtained.
