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

Author affiliations

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.
