Abstract. Dye adsorption and microstructure of TiO2 film are important properties when it is used as photoelectrode of dye-sensitized solar cells (DSCs). This study investigated the application of a low crystallinity TiO2 film in DSCs. The low crystallinity TiO2 film is composed of interconnected spherical particles with an average size of 20 nm and has homogeneous mesoporous inner structur…
