Abstract
The aim of this study is to harness and store solar energy through Indigo Carmine dye–Formic acid photogalvanic cells. The photogalvanic cells based on photo-sensitizer Indigo Carmine dye-surfactant Sodium Lauryl Sulphate-reductant Formic acid–NaOH alkaline medium has shown encouraging and very impressive improvement in solar energy conversion and storage. This combination of chemicals has shown harnessing of 985.6 μW maximum powers with a storage capacity of 115 min as half change time from the 10.4 mWcm−2 artificial and low illumination intensity. In this study, the observed optimum cell performance in terms of the maximum potential, maximum photocurrent, and short-circuit current is 1086 mV, 6400 μA, and 3800 μA, respectively.
