A charge transferor of a solar cell, which collects and transfer charges generated from a semiconductor substrate, includes at least one electrode collecting the charges; and at least one collector transferring the charges collected by the at least one electrode, the at least one collector being included in at least one collector region on the substrate, wherein the at least one collector region in a first direction comprises at least one deletion portion where the at least one collector is not formed.
摘要:
A solar cell is discussed. The solar cell includes a base substrate containing first impurities of a first conductive type and having a textured surface, an emitter layer that is positioned at the textured surface of the base substrate and contains second impurities of a second conductive type different from the first conductive type, and a front electrode electrically connected to the emitter layer. The front electrode collects carriers generated in the base substrate or the emitter layer. At least a portion of the front electrode transmits incident light from the outside.

A solar cell includes a substrate of a first conductive type, an emitter region of a second conductive type opposite the first conductive type and which forms a p-n junction along with the substrate, an anti-reflection layer positioned on the emitter region, a front electrode part electrically connected to the emitter region, and a back electrode part electrically connected to the substrate. The substrate includes a first area formed of single crystal silicon and a second area formed of polycrystalline silicon. A thickness of the anti-reflection layer positioned in the first area is less than a thickness of the anti-reflection layer positioned in the second area.
