Electricity generation and stability of dye-sensitized solar cells (DSSCs) employing indigofera as sensitizers

The goal of this study is to assess the performance and stability of solar cells incorporating Indigofera dyes in terms of energy production. Indigofera is a natural dye was created through the fermentation of Indigofera leaves. The stability test was carried out using a heat treatment at 50°C for 100 hours. Indigofera is a natural dye were tested for absorbance, FTIR, and cyclic voltammetry. Indigofera dyes were then added on dye-sensitized solar cells (DSSCs), and the performance of the DSSCs was assessed after 0 hours and following 100-hour heat treatment at 50°C. Indigofera natural dye solar cells had open circuit voltage (Voc), short-circuit current (Isc), and efficiency of 370 mV, 0.056 mA/cm², and 0.01%, respectively. When DSSCs were heated to 50°C for 100 hours, their efficiency dropped by 80%.
