摘要: A method of fabricating a solar cell includes forming an emitter layer of a second conductive type on a front surface and a back surface of a substrate of a first conductive type opposite to the second conductive type, forming an anti-reflection layer on the front surface of the substrate, partially removing the anti-reflection layer and the emitter layer to form an isolation groove dividing the emitter layer into a plurality of regions, removing a portion of the emitter layer formed on the back surface of the substrate, and forming a passivation layer covering the isolation groove and the back surface of the substrate.
