High efficient dye sensitized solar cells typically apply expensive materials. To reduce the costs natural dyes, carbon nanotubes and an additional contact layer were introduced. UV-irradiation substitutes typical sintering processes for the TiO2 nanoparticle film. Replacing the ITO coated glass electrodes by a metal grid structure reduces the integration costs further more. Best results were achieved using a grid structure with openings in the dimension of the diffusion length of the charge carriers.
