Study of the enhancement on photogalvanics: solar energy conversion and storage in EDTA–safranine O–NaLS system

Abstract

The study focused on exploiting modified cell fabrication parameters for enhancing the solar power generation and storage capacity of a photogalvanic ethylene diamine tetraacetic acid–safranine O–sodium lauryl sulphate chemical system. This chemical system with changed concentrations, a combination electrode and a very small Pt electrode was used to fabricate a modified photogalvanic cell. The modified cell showed greatly enhanced performance (i.e., that for pre-modified cell) in terms of charging time (40 min), initial generation of photocurrent (260 μA min⁻¹), equilibrium photocurrent (1700 μA), power (364.7 μW), half change time (40 min), and efficiency (8.93%). The effect of various cell fabrication parameters was studied for optimization of the value of fabrication variables for the optimal cell performance based on the proposed mechanism.
