Sodium Lauryl Sulphate Enhanced Solar Energy Conversion by Photogalvanic Effect of Rhodamine B‐Fructose in Artificial Light

Abstract

The present study has been done to improve the solar power and storage capacity of the Rhodamine B‐Fructose system with small Pt electrode by use of Sodium Lauryl Sulphate surfactant in the artificial light. With additional scope for reduction of the cost, the present study has shown greatly enhanced performance in terms of electrical parameters like power 336.05 μW, short‐circuit current 1150 μA, and conversion efficiency ∼11.28 %.

Use of Pigments Present in the Crude Aqueous Extract of the Spinach for the Simultaneous Solar Power and Storage at Natural Sun Intensity

The unique property of PG cells lies in their capacity to be charged at low intensity (inside room) as well as to work as a power storage device.The PG cell technique consists of two dissimilar electrodes dipped in the very dilute electrolyte solution containing artificial/natural photosensitizer(s), reductant(s), alkali (NaOH), and surfactant(s). Photovoltaic (PG) conversion by a macromolecular thionine organic dye film photosensitizer-ferrous salt inorganic reductant chemical system, [5] a tolusafranine organic dye photosensitizer-ethylenediaminetetraacetic acid (EDTA) organic reductant system, [6] and a thionine dye photosensitizer solution-ferrous salt inorganic reductant chemical system [7] has been reported.The PG cell based on various inorganic compounds, [8][9][10][11] organic dye photosensitizers with organic reductants, [12][13][14][15][16] and surface-active reagents dissolved in the water (prepared from deionization followed by distillation in the presence of KMnO 4 ) has been widely studied. A new photosensitizer (metanil yellow)-reductant (formic acid) couple in the PG cells-has also been recently reported.

Tropaeline O‐oxalic acid‐benzalkonium chloride photogalvanic cells for solar energy conversion and storage

“…The kinetics of the photo-decay and deactivation of these excited species here is estimated to be of nonzero order. 38 In Table 3, the 620-700 µA enduring current is here for a single PG cell. For commercial use, the required current value can be realized by assembly formation of individual PG cells as is done in the case of PV cells.…”

Experimental study on the thermal performance and heat transfer characteristics of solar parabolic trough collector using Al2O3 nanofluids

“…With the aim of identifying an ideal energy storage material in solar heat collectors, Koli [1] studied the heat storage capacity of rhodamine B-fructose with Pt electrode and sodium lauryl sulfate as surfactant, with a resulting enhancement in system performance of the PG cell by 11.28%. One of the major challenges in solar energy is that it can be harnessed only during day time.…”

“…To extend the utilization of solar PTCs, the introduction of heat storage techniques (PCM, brine water, and chemical storage systems) has made it possible to store the energy in day time and radiate the stored energy at night and when cloudy. With the aim of identifying an ideal energy storage material in solar heat collectors, Koli [1] studied the heat storage capacity of rhodamine B-fructose with Pt electrode and sodium lauryl sulfate as surfactant, with a resulting enhancement in system performance of the PG cell by 11.28%. The use of FCF and fructose as surfactants in a Pt electrode photo galvanic (PG) cell increased performance by 6.59% [2].…”
