Abstract
Disclosed is a solar cell including a control passivation film on one surface of a semiconductor substrate, and being formed of a dielectric material; and a semiconductor layer on the control passivation film, wherein the semiconductor layer including a first conductive region having a first conductive type and a second conductive region having a second conductive type opposite to the first conductive type. The semiconductor substrate includes a diffusion region including at least one of a first diffusion region and a second diffusion region adjacent to the control passivation film, wherein the first diffusion region being locally formed to correspond to the first conductive region and having a doping concentration lower than a doping concentration of the first conductive region, wherein the second diffusion region being locally formed to correspond to the second conductive region and having a doping concentration lower than a doping concentration of the second conductive region.
