At the same time of the perovskite discovery to function as efficient light harvester in the solar cell, Etgar et al.  first proposed a heterojunction device structure of FTO/TiO2/CH3NH3PbI3/Au in which CH3NH3PbI3 was used as a p-type semiconductor and 500 nm mesoscopic TiO2 was used as an n-type semiconductor.
