Abstract The films which consist of the semiconductor nanoparticles possess vast specific surface area and a large amount of dye molecules can be adsorbed on the surface. As a result, the sunlight can be absorbed by the dye molecules and transformed to electricity efficiently. The principles and structures of the dye sensitized solar cell are introduced as well as its development and present situation of research.
