A solar cell structure includes a substrate, a buffer layer on the substrate, a type II band alignment nanostructure layer on the buffer layer, a p-type area and an n-type area defined on the type II band alignment nanostructure layer, and a p-type metal electrode and an n-type metal electrode coated onto the p-type and n-type areas, respectively. The type II band alignment nanostructure layer is provided for distributing an electron current and a hole current in different channels to minimize the recombination of electrons and holes and improve the photoelectric conversion efficiency of the solar cell significantly.
