Solar power can easily meet the demands of electrical power for whole world if only we could decrease the power to price ratio for solar panels [1]. One of the possible way is to reduce the production cost and as so the third generation of solar cells such as dye sensitized solar cell (DSSC) [2] and quantum dots solar cell (QDSC) [3] were introduced. Nonetheless there are still some issues to be overcome. The typical structure of DSSC and its simple adaptation for QDSC is based on glass with transparent conductive oxide (TCO) layer and then using screen printing as a cheap and fast method a mesoporous layer of TiO2 is deposited. This process although being used very often especially for DSSC does not provide a good interface quality of heterostructure of TCO layer and photoanode layer. So far the particles size of TiO2 was mainly studied in order to increase the adsorption of dye [4], or diffusion and recombination in dye-sensitized TiO2 solar cells [5]. In our work we mainly focus on increase of the charge transfer in order to increase final efficiency.
