Fabrication and Studies on FTO/(Compact ZnO/Porous ZnO: Eosin-Y)/C: FTO Solar Cell

ABSTRACT

Dye sensitized solar cells (DSSC) are photoelectrochemical solar cells. They are based upon an iodide tri-iodide redox couple mediated between a photosensitive electrodes of semiconductor materials stained with a photosensitive dye and a catalytic counter electrode. In the present investigation, ZnO compact layer was deposited using chemical solution deposition (CSD) method followed by porous ZnO layer by doctor blade (DB) method. Eosin-Y dye was used to sensitize ZnO films. DSSC fabricated using ZnO nanostructures with both, compact and porous layers (FTO/(Compact ZnO/Porous ZnO: Eosin-Y)/C/FTO), exhibited a conversion efficiency of ∼ 1.20% under 100 mW/cm².
