The recent technological advancements of the Dye Sensitized Solar Cells (DSSCs) fabrication technology is gaining momentum as a low cost and simple fabrication technology to convert solar energy into electric energy. A systematic study of the DSSC fabrication procedure and its influence on the cell efficiency are presented in this paper. Preparation of the titanium dioxide (TiO 2α layer on the working electrode was the most significant process improvement made to enhance cell efficiency. The Coatema tool was used to develop an automated TiO 2 coating process, which yielded layer thicknesses with minimum micro cracks and repeatable TiO 2 weight loading in the range of 8-13 μm. Secondary process improvements implemented were: vacuum drying step for the TiO 2 layer, dilution ratio of the sensitized dye and sealant thickness. These optimized cell fabrication steps enhanced cell efficiencies over 200% and reduced total process time. The work in progress demonstrated higher cell efficiency slightly greater than 9% by reducing the cell size using the optimized fabrication process described in this paper. We are confident that higher efficiency cells can be fabricated with this optimized fabrication process illustrated in this paper.
