| 摘要 |
A solar cell and method of fabrication are disclosed. In one embodiment of the present invention, the method comprises depositing a first doped amorphous silicon layer on a first surface of a silicon substrate, depositing a second doped amorphous silicon layer on the first surface of the silicon substrate. The second doped amorphous silicon layer is doped oppositely from the first doped amorphous silicon layer. An anneal is performed to transform the first doped amorphous silicon layer and second doped amorphous silicon layer to crystalline silicon layers.
