The Efficiency of Dyes Sensitized Solar Cells Using Different Sensitized Dyes

Abstract

Manufacturing techniques of solar cell have been developed rapidly since their first appearance. Dyes sensitized solar cell (DSSC) is a modern technique of solar cell .It optimized by their low manufacturing cost and the high power conversion. In this paper three of DSSC were fabricated using three different sensitized dyes Cumarin 500 , Alcian Blue 8GX and Bangal Ross B Sodium Salt. The absorbance of each DSSC was determined by Ultraviolet- visible spectrometer. The short circuit voltage and current were measured for each sample to determine which of the dyes has the best efficiency of power conversion. The results also obtained the fill factor for each of DSSCS. The results showed the fill factor and the bandgap of each sample. The voltage and current results reflect that Bangal Ross has the highest efficient of the other dyes.
