Application of Screen Printing to Prepare Photoanode for Dye-Sensitized Solar Cells

Dye-sensitized solar cells (DSSCs) have the advantages of low cost, long life and no pollution. In recent years, DSSCs have rapidly developed into solar cells with commercial application prospects. Photoanodes have a critical impact on the performance of DSSCs. In this paper, photoanodes were prepared by screen printing. The size of titanium oxide, number of screen printing layers, mesh number in photoanode were studied. The surface thickness was observed by laser confocal microscopy, and the most suitable screen printing conditions were selected according to the photoelectric conversion efficiency of dye-sensitized solar cells. The researchon the preparation of DSSCs by screen printing provides an effective way for large-area industrial preparation of DSSCs.
