Solar cell and method for forming solar cell emitter comprising pre-amorphization and ion implantation |
摘要 |
A method for manufacturing a solar cell according to an embodiment of the present invention includes preparing a semiconductor substrate having a first conductive type dopant; ion-implanting a pre-amorphization elements into a front surface of the semiconductor substrate to form an amorphous layer; and forming an emitter layer by ion-implanting second conductive type dopant into the front surface of the semiconductor substrate. The method then further includes heat-treating the layers to activate the second conductive type dopant. The method further includes forming a back surface field layer at a back surface of the semiconductor substrate by ion-implanting a first conductive type dopant. |
