Highly sensitive, multicomponent broadband photodetector devices are made from PbSe/graphene/TiO 2 . TiO 2 and PbSe nanoparticles act as light harvesting photoactive materials from the UV to IR regions of the electromagnetic spectrum, while the graphene acts as a charge collector for both photogenerated holes and electrons under an applied electric field.
