摘要：

Bromophenol Red is used as a photosensitizer in a photogalvanic cell for solar energy conversion. EDTA was used as an electron donor. The photopotential and photocurrent generated by the cell are 581.0 mV and 45.0 mu A, respectively. The effects of various operating parameters, e.g. pH, light intensity, diffusion length, reductant concentration, dye concentration, on the electrical output of the cell is examined. The current-voltage (i-V) characteristics of the cell are also observed and a tentative mechanism for the generation of the photocurrent is proposed. The performance of the cell is determined in the dark at its power point. (c) 2005 Elsevier B.V. All rights reserved.
