Fabrication and characterization of Tio2 based dye sensitized solar cells

Abstract

Currently the world consumes an average of 13 terra watts TW of newlineelectric power by the year 2050 this amount is likely to be 35 TW newlinePhotovoltaic power generation is one of the best suited methods and it has newlineseveral advantages notably that it does not produce any harmful pollutants newlinesince the sun deposits 1 20 000 TW of radiation on the earth At present more newlinethan 95 of crystalline Silicon solar cells are in use but the cell efficiency is newlineless and the cost is high In order for solar cells to become more widely newlineadopted it is necessary to either bring down its cost or increase its efficiency newlinethrough the use of new designs newlineThe third generation Dye Sensitized Solar Cells DSSC newlineTechnology finds an efficient and economical way to directly convert solar newlineenergy into electricity The advantages of DSSC over silicon cell are low cost newlineease of production increase in performance with temperature bifacial newlineconfiguration advantage of diffuse light transparency for power windows newlinethe colour of the refracted light from the cell can be varied by selection of the newlinedye etc newline newline
