This study explores the design and experimental analysis of a solar cell utilizing titanium dioxide (TiO2) as the semiconductor material and natural beetroot dye as the photosensitizer. The investigation encompasses the fabrication of a dye-sensitized solar cell (DSSC) by depositing a TiO2 film on a conductive glass substrate. The natural dye extracted from beetroot is employed to sensitize the TiO2, harnessing its light-absorbing properties. The DSSC is assembled by sandwiching the TiO2-coated glass with a counter electrode and an iodide-based electrolyte. Experimental measurements of open-circuit voltage (Voc) and short-circuit current (Isc) are conducted, and current-voltage (I-V) characteristics of the solar cell are analyzed under varying light conditions. The results demonstrate the feasibility of using natural beetroot dye as a photosensitizer in DSSCs and provide insights into the performance of such eco-friendly solar cells, contributing to the field of sustainable energy technologies.
