Effect of solvent type and annealing temperature on efficiency for eosin-y dye sensitized solar cell

Abstract EN

Dye-sensitized solar cell (DSSC) is one of the photochemical electric cells, which consists of the photoelectrode, the dye, the electrolyte, and the counter electrode.

The advantage of DSSC is the low cost of the solar energy conversion into electricity because of inexpensive materials and the relative ease of the fabrication processes.

In this study was selected solvent dye resolve to know most efficient in terms of conversion efficiency.

A dye solution of water or ethanol and maxing in which eosin – y dissolves behaves like a colloid and explores the effect of sintering temperature of TiO2 films on the efficiency of dye sensitized solar cells.

A study conducted on several samples at different temperatures.

Exemplary efficiency of the cell in a water solution of the dye effect of heat annealing 450 0C was found 0.73%, but after the addition of AgNO3 improved efficiency to 1.1 % .
