A solar cell includes a p-n structure having a first conductive semiconductor substrate, a second conductive semiconductor layer formed on the first conductive semiconductor substrate and having a conduction opposite to the first conductive semiconductor substrate, and a p-n junction formed at an interface between the first conductive semiconductor substrate and the second conductive semiconductor layer; a passivated layer formed on the second conductive semiconductor layer and composed of silicon oxynitride with a refractive index of 1.45 to 1.70; an anti-reflection film formed on the passivated layer and composed of silicon nitride; a front electrode connected to the second conductive semiconductor layer with passing through a part of the passivated layer and the anti-reflection film and exposed outward; and a rear electrode formed at an opposite side to the front electrode with the first conductive semiconductor substrate being interposed therebetween to be connected to the first conductive semiconductor substrate.
