The synthetic dyes as photo‐sensitizers have been extensively studied in the photogalvanic cells for solar energy conversion and storage in artificial light. To make photogalvanic cells more environmentally friendly and sustainable, the natural and renewable source like crude extract of the spinach has been studied as sensitizer material in this study. Remarkable steady state power and current generation with simultaneous power storage have been observed. The observed cell performance (charging time 18 min, Open‐circuit potential 1050 millivolt, Short‐circuit current 1750 micro ampere, power 384.0 micro watt, storage capacity as half change time 44 min, efficiency ≈ 9.22%) is very encouraging to photogalvanics. This study shows that the natural resources like crude spinach extract can also sensitize photogalvanics with efficiency as high as for synthetic dye sensitizers with additional advantage of low cost and free from pollution, which is associated with production and disposal of dyes. Natural resources like crude spinach extract‐based PG follow same principles as for synthetic dye sensitizers. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 1800–1807, 2018

“…It is intended to be achieved by blackening H‐cell externally and keeping a small window for illumination of Pt electrode. Furthermore, the higher diffusion retards energy wasting reverse reaction (electron transfer from Pt electrode to dye, and from dye to reductant in illuminated chamber) and increases i sc leading to improvement in overall performance of the cell …”

Solar cell converts solar energy into electricity directly. Among such solar cells, the photogalvanic cells are unique as these are only solar cells that are capable of doing solar power generation and storage simultaneously. Therefore, such an inherent solar power storage capacity that too with good efficiency of these cells needs to be exploited for making solar cell technology a reliable source of power in the future. The fabrication and experimentation of photogalvanic cells is very simple to demonstrate its unique property. The power, short-circuit current, open-circuit potential, conversion efficiency, and power storage (in terms of half change time) for photogalvanic cells are reported of the order of 1159 μW, 4500 μA, 1.07 V, 14, and 260 min, respectively. However, to make photogalvanic cells realty in life for simultaneous solar power and storage, some challenges have to be tackled. Some of the challenges are photodecay of dye, corrosion of platinum (Pt), evaporation of liquid, breaking vulnerability of SCE/combination electrode, further need to increase the power and efficiency and storage, assembly operation of cells for augmentation of power, cell study in natural sunlight, and so on.

SUMMARYThe studies of the micellar effect on photogalvanics was done for solar energy conversion and storage in photogalvanic cell containing dioctyl sodium sulphosuccinate as anionic micellar species, EDTA as reductant and safranine O as photosensitizer. The photopotential and photocurrent generated were 800.0 mV and 65.0 mA respectively. The observed conversion efficiency was 0.2532 per cent, the fill factor was 0.38 and the maximum power of the cell was 52.0 mW whereas the power at power point of the photogalvanic cell was 26.34 mW. The rate of initial generation of current was 37.5 mA min À1 . The photogalvanic cell can be used for 80.0 minutes in the dark. The effects of different parameters on the electrical output of the photogalvanic cell were observed and a mechanism has also been proposed for the generation of photocurrent in the photogalvanic cell.
