Fabrication of solar cell utilizing digital fabrication technology

Solar cell is one of the key technologies in this century because this has possibility to clear energy problems. In this paper, we tried to fabricate TiO₂ layer of solar cell utilizing digital fabrication technology. The digital fabrication technology is an inkjet fabrication method. Our inkjet technology has good merit; that is ability to eject highly viscous liquid. We applied the inkjet technology for fabricating TiO₂ layer on FTO glass. The thickness of TiO₂ layer was controlled by the time to print.
