The aim of research work was to convert and store the photogalvanic energy by alizarin red-s - NaLS - ascorbic acid. The photogalvanic cells are based on photoelectrochemical nature. This study is better over reductant system i.e., ascorbic acid. The obtained results are comparatively better for sustainable application. M/5000 solution of alizarin red-S, M/1000 solution of NaLS and M/1000 solution of ascorbic acid were used for experimental observation. The fill factor (FF) and conversion efficiency (CE) were calculated for alizarin red-S - NaLS - ascorbic acid system and results were 0.2731 and 1.8970 %, respectively. The electrical outcome was relevant to power, open- circuit voltage, and short circuit current for alizarin red-S - NaLS - ascorbic acid system in solar photogalvanic performance and storage. These results are 197.29 µW, 1075 mV, 672 µA, respectively. The photo-excitation of alizarin red-S molecules was studied in solar performance and storage for photoelectrochemical process.
