Solar Energy Conversion and Storage by Photogalvanic Cell

Today, the rapid decrease in energy resources caused by the large-scale consumption of fossil fuels has become serious. Accordingly renewable energy resources are attracting a great deal of attention, and solar energy is one of the most promising future energy resources. The photochemical production of electricity has attracted the attention of many scientists as a viable media for solar energy conversion. In this book, we studied the photogalvanic effect using iron acetyl acetonate complex and Rose dye as photosensitizer. The first system consists of iron acetyl acetonate complex – Oxalic acid – Tween 80 System and the second one containing Rose Bengal-Oxilc acid-Cetryl hexadecyl ammonium bromide. The photopotential and photocurrent obtained from the first system were 404.20 mV and 35.0 μA respectively. The observed power of the cell was 12.69 μW at power point. The conversion efficiency and fill factor was determined as 0.04% and 0.33 respectively. The cell performance was 35.0 min in dark. The generated photopotential and photocurrent of the second system were 550.0 mV and 75.0 μA respectively. The observed power of the cell was 41. 3 μW at power point.
