All Screen Printed Dye Solar Cell

摘要

All screen printed Dye Sensitized Solar cell modules were fabricated and demonstrated excellent electrical performances thanks to a monolithic interconnection based on highly conductive carbon layers. Attained efficiency at 1000 W/m~2 is 6 % with a fill-factor of 0.7. This monolithic module is very elegant to manufacture since the layers, including nano-TiO_2 spacer, catalytic active layer, conductive carbon and sealing are all printed. Such a module only requires one transparent conductive substrate which allows substantial manufacturing cost reductions. Moreover, only one co-firing cycle is sufficient, thus lowering the required energy at production. In addition, a quick staining process enables in-line production techniques. Modules of 10 × 10 cm are now being built for sampling and performance testing.
