Fabrication of a dye-sensitized solar cell module using spray pyrolysis deposition of a TiO2 colloid

Abstract

We provide a complete illustration of dye-sensitized solar module fabrication by spray pyrolysis deposition (SPD) of a TiO₂ colloid having ∼10 nm sized TiO₂ nanoparticles. The process was first optimized for cell level fabrication, and the parameters (mainly the thickness) obtained from the study were subsequently used for module level fabrication. The best efficiency obtained at the cell level (area 0.2 cm² and thickness of 12 μm) was 7.79% and that for the (12 cm × 12 cm) module was 3.2%.
