The screen-printed nanoporous TiO₂ thin film was employed to fabricate dye-sensitized solid-state solar cells using CuI as hole-transport materials.The solar cell based on nanoporous TiO₂ thin film with large pores formed by the addition of polystyrene balls with diameter of 200 nm to the TiO₂ paste exhibits photovoltaic performance enhancement, which is attributed to the good contact of CuI with surface of dye-sensitized thin film due to easy penetration of CuI in the film withlarge pores.
