A maximum energy-conversion efficiency (η) of 3.73% is achieved from solar cells fabricated with 3 mol% Zn-doped meso-SnO2 photoanodes, a nearly five-fold improvement compared to undoped meso-SnO2 photoanode DSCs (η = 0.81%).Dye-sensitized solar cells (DSCs), based on wide band gap metal oxide semi-conductor and redox couple electrolyte, have been regarded as a green and cost-efficient way of solar to electric energy conversion.

For preparation of photo-electrode, a mesoporous film of anatase TiO2 coating on the FTO glass substrate was fabricated by sol–gel process according to the literature An active area of 0.25cm2 TiO2 was selected from sintered electrode, immersed in a co-solvent of ACN/t-butanol (1:1 by volume) containing 0.3mM Ru1A, Ru11A, Ru2A, Ru3A and N3 dyes, respectively for 24h, rinsed with acetone and dried.
