Transparent /reflector TiO2 film contains ~5 µm of reflector TiO2 particles and ~7 µm layer of TiO2 nanoparticles with average size of 20 nm, deposited on FTO glass. The scattering layer increases light harvesting efficiency. This electrode can be used as a standard photo-anode to evaluate dye molecules, quantum dots, electrolyte and different cathodes for dye sensitized solar cells. Annealing at 500 °C is recommended prior to use.
