Abstract Natural dye–sensitized solar cells (NDSSCs) are considered promising third-generation photovoltaic devices due to their potential to produce environmentally friendly energy at relatively low manufacturing costs. Their fabrication process does not require highly sophisticated or expensive equipment, making them economically attractive. This paper presents a review of the design and working mechanism of curcumin-based dye-sensitized solar cells. The primary aim of this study is to capture and store solar energy using a natural dye system composed of curcumin, fructose, and Brij-35 in a photogalvanic cell. When operated in an alkaline medium, the photogalvanic cell demonstrates significant enhancement in both solar energy conversion efficiency and energy storage capability. The chemical system demonstrated a maximum output power of 120.50 µW, with an energy storage capacity lasting up to 100 minutes, measured as the half-discharge time under 10.4 mW cm⁻² artificial low-intensity illumination. The optimal performance of the cell was recorded with a photopotential of 918 mV and an equilibrium photocurrent of 784 µA. Aditionally, the device achieved solar energy conversion efficiency and fill factor 1.15% and 0.1436 respectively.
Keywords Natural Dye Sensitized solar cell, Curcumin, Fructose, Brij-35, Sustainable development, Photogalvanic effect, fill factor, conversion efficiency.
