Optimum Efficiency of Photogalvanic Cell for Solar Energy Conversion: Lissamine Green B-Ascorbic Acid-NaLS System

Abstract

Photogalvanic cells are photoelectrochemical cells chargeable in light for solar energy conversion and storage. They may be energy source for the future, if their electrical performance is increased. In this study, a photosensitizer Lissamine green B, a reductant Ascorbic acid and a surfactant NaLS have been used in the photogalvanic cell. The generated photopotential and photocurrent are 850.0 mV and 375.0 μA respectively. The conversion efficiency of the cell, fill factor and the cell performance were observed 1.0257%, 0.2598% and 170.0 minutes in dark respectively. The effects of different parameters on the electrical output of the photogalvanic cell were observed. A mechanism was proposed for the photogeneration of electrical energy.

Simultaneous electrochemical solar power generation and storage using metanil yellow-formic acid as a new sensitizer-reductant couple in photogalvanic cells

“…In the present work, the optimum cell performance in terms of electrical parameters is i max 6000 mA, i sc 3600 mA, V oc 1105 mV, P pp 822 mW, and CE 20.41%. The results in the present work are higher with respect to previous work 16,[27][28][29]37 and are also consistent with the aim of undertaking this work to further increase the electrical performance of PG cells. The results of the present study are sufficiently novel to report advancement over previous results (Table 9), viz., (a) P pp 649.6 mW, CE 8.12%, and power storage capacity 59 minutes, 37 (b) P pp 158.9 mW, V oc 960.0 mV, i sc 350.0 mA, and CE 1.52%, 27 (c) P pp 93.15 mW, V oc 919 mV, i sc 210 mA, and CE 0.8967%.…”

Use of Natural Dye Curcumin – Arabinose as Photosensitizerreductant System for Simultaneous Solar Energy Conversion and Storage

“…The problems encountered in the development of photogalvanic cells have been discussed from time to time. Krasnoholovets et al [17], Madhwani et al [18], Gangotri and Bhimwal [19], Genwa and Chauhan [20], Genwa and Singh [21], Rathode et al [22][23] and Yadav et al [24][25][26] have recently developed some photogalvanic systems for solar energy conversion and storage. The scientific community has successfully converted solar energy in electrical energy up to desired extent through various processes but storage capacity of solar energy is still not up to the mark to use it as and when required.…”
