Creation of Natural Dye Sensitized Solar Cell by Using Nanostructured Titanium Oxide

摘要

This present study focused on improving the methodology of producing chlorophyll dye-sensitized solar cells by the process of amalgamation with anthocyanin dyes. This is done with the hope of maximizing cell efficiency and sustainable power production for mass manufacturing processes at the most economical cost. The construction of dye sensitized solar cells is a three-step process comprising: dye extraction, TiO₂ paste application, and solar cell structure. These three important factors contribute significantly to the efficiency maximization of a dye-sensitized solar cell. The research conducted specifically explored different ways of improving the current-voltage potential of the solar cells. The solar cell's performance in terms of efficiency and power output (voltage vs. current) was tested under an indoor room light, a halogen lamp and direct sunlight. The experimental results show that the dye extract from Green Cabbage produced the greatest photoelectric conversion efficiency (η) of up to 0.1%, an open-circuit voltage (V_oc) of 532 mV, and a short-circuit current density (J_sc) of 1.2?mA/cm2.
