Hybrid solar cell skeleton, energy level distribution, and SEM images of device and hybrid film surface. (a) Left: the skeleton of hybrid solar cells in this work, right: the corresponding energy level distribution of the whole device. (b) SEM image of the cross section of the device showing the layered structure of the hybrid solar cell (ITO/CdTe/CdTe: CdSe/ZnO/Al). (c) SEM image of hybrid film surface without (left) and with (right) MPA treatment.
