DETAILED DESCRIPTION - The solar cell comprises a semiconductor substrate (1) comprising a first conductive type material, a semiconductor layer comprising a second conductive type material formed on a front surface of the semiconductor substrate, antireflective layers (3) formed on the semiconductor layer, a front electrode (4) passing through the antireflective layer and contacting the semiconductor layer, and a rear electrode (5) formed on a rear surface of the semiconductor substrate. The first conductive type material is different than the second conductive type material. The semiconductor layer has a depth of 100-500 nm, and a sheet resistance of 60-120 Omega /square. The first conductive type material is p type, and the second conductive type material is n type. The second conductive type material of the semiconductor layer has an impurity concentration gradient of 1x 1016 to 1x 1021 atom/cm3 from a front surface of the conductive layer to a p-n junction interface between the conductive layer and the conductive substrate. A composition of the front electrode is different than the composition of the rear electrode. A dielectric layer (7) is formed between the front electrode and the antireflection layer.
