The photogalvanic effect was studied in photogalvanic cell containing orange G as Photosensitizer, sodium lauryl sulphate and EDTA as reducing agent. The photo-outputs with EDTA are higher for Solar Energy Conversion and Storage. The current-voltage relations of the cell have been measured in the dark and light under both forward and reverse direction. The photo potential and photocurrent generated was found to be 960.0 mV and 350.0 µA, respectively. The observed conversion efficiency was 1.52% fill factor and the maximum power of cell was 0.47 µA and 158.9 µW. The storage capacity of the cell was 80.0 minutes in dark. A mechanism was proposed for the generation of photocurrent in photo galvanic cell.

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.

“…Gangotri and Bhimwal [17] have studied the performance of a photogalvanic cell using a rose bengal d-xylose-sodium lauryl sulphate (SLS) system. Madhwani et al [18][19][20] have used fuschin basic, rose bengal and fluorescein-ethylenediaminetetraacetic acid systems, in photogalvanic cells for solar energy conversion and storage. The effect of using two reductants in photogalvanic cells has been reported by Dubey [21], Gangotri and Indora [22], and Gangotri et al [23], while the use of two dyes in photogalvanic cells has been reported by Gangotri and Lal [24], and Lal and Yadav [25].…”

Sodium lauryl sulphate (SLS) was used as a surfactant, thymol blue as a photosensitizer and mannose as a reductant in a photogalvanic cell to improve the conversion efficiency and storage capacity of such cells to achieve commercial viability. The photopotential and photocurrent generated were 635.0 mV and 100.0 µA, respectively. The effect of various parameters including concentration of photosensitizer, reductant and surfactant, pH and diffusion length on the cell properties was observed. The observed conversion efficiency and the maximum power of the cell were 0.23% and 24.60 µW, respectively. The fill factor was 0.25 at the power point of the cell. The photogalvanic cell can be used for 37 minutes in the dark following illumination for 120 minutes. The current-voltage characteristics of the photogalvanic cell were studied experimentally. All of the results observed for the system were lower in absence of surfactant. The absorption spectra of the systems with and without surfactant were also studied.
