THE STUDY OF PHOTOELECTROCHEHICAL CELLS BASED ON CHLOROPHYLL AND ORGANIC DYES

Tetraiodofluorescein(TIF)and safranine T(ST)had great effects on the photovoltaicparameters of the cells.The Voc of the cells was about 3-5 times higher than that of thecells without TIK and ST,Isc increased 1 to 2 orders of magnitude.The Voc and Isc couldbe increased greatly only when Voc and Isc of the cell with Pt as WE properly combinedwith the Voc and Isc produced by chla in the original cell.According to absorption spectraand output characters,the results were elucidated.
