Dye Sensitized Solar Cell Structure

The solar energy to power conversion efficiency of a dssc is influenced by various components of the cell such as the dye electrolyte electrodes and additives among others leading to varying experimental configurations.
Dye sensitized solar cell structure. It is based on a semiconductor formed between a photo sensitized anode and an electrolyte a photoelectrochemical system. In this research efficiency enhancement of dye sensitized solar cell dssc with ag doped tio 2 core shell c s as plasmonic photoanode structure abbreviated as ag tio 2 was investigated using sol gel dr blade method different amount of ag in two different thick of photoanode were applied to enhance the light absorption for high performance dsscs. Dye sensitized solar cells 4 have attracted great interest because of their potential application as a cost effective alternative to p n junction solar cells 5.
