Abstract

The world’s energy needs are increasing as the human population increases. The fulfillment of fossil-based energy has reached optimal conditions and is predicted to decline in the future. One potential that can be developed to meet future energy needs is dye-sensitized solar cell (DSSC). DSSC is an efficient third generation that produces green energy at low production costs because no vacuum system or expensive equipment is required to manufacture. This study examines the structure of the DSSC using indium tin oxide (ITO) glass, and its working principles are described. The dye solution uses curcumin as the photosensitizer. From the results of this study, it is known that DSSC at a sintering temperature of 400°C has better results than DSSC with a sintering temperature of 350°C. The DSSC with turmeric ( Curcuma longa) has an efficiency of 0.81%.
