Nature and effect of dye sensitizer in solar energy conversion and storage in Photogalvanic Cell: Brilliant Green - Ascorbic acid - ALES System
TLDR
In this paper, solar energy conversion through photogalvanic effect and its storage by using photoglvanic cell was studied in Brilliant Green - Ascorbic acid - ALES System.Abstract:
Solar energy conversion through Photogalvanic effect and its storage by using photogalvanic cell was studied in Brilliant Green - Ascorbic acid - ALES System. The ascorbic acid as a reductant, Brilliant Green as dy e sensitizer and Ammonium Lauryl Ether Sulphate as surfactant in aqueous solution. T he photopotential and photocurrent generated were 611.0 mV and 720.0 µA respectively. The observed power of the cell was 262.40 µW at its power point. The conversion efficiency and fill factor was determined as 2.52% and 0.29 respectively. The cell performance was 180.0 min. in dark. A mechanism for the Photogeneration of electr icity has also been proposed. The effects of different parameters on the electrical o utput of the cell and current-voltage (i- V) characteristics of the cell were studied.read more
