  1. Dye-sensitized solar cells Jouko Korppi-Tommola Jani Kallioinen Pasi Myllyperkiö Henriette Santa-Nokki

  2. Counter electrode Platinized conductive nanoparticles (Pt-SnO2:Sb) Spread Pt-SnO2:Sb Cut & Clean substrates Press Other components Hotmelt frame Electrolyte Assembly DSSC Preparation scheme for DSSC on conductive plastics Photoactive electrode: Ruthenium dye-sensitized TiO2 film Cut & Clean substrates Spread TiO2 Press Sensitization

  3. Dynamic press Cond. substrate TiO2 Laboratory paper calender Pressing of electrode materials Static press Pressure Press plate TiO2 Cond. substrate Metal plate Hydraulic press

  4. Examples of studied issues: • Spreading methods • Control coater • Film applicator • Gravure printing • Composition of the pastes • Viscosity (solid content, solvent) • Additives (cellulose) • Film thicknesses • TiO2 • Pt-ATO • Electrolyte • Solid, gel or liquid

  5. Electrochromic cells on ITO-PET Dye-sensitized TiO2 stripes on ITO-PET

  6. Research on solar collector efficiency Flat plate, vacuum, black liquid, black rubber collectors Vaajakoski research laboratory
