Abstract
A method of fabricating a solar cell on a conveyer belt is provided. The method includes the following steps. A first surface of an aluminum foil is coated with a layer of phosphorous mixed with a plurality of graphite powders and put on the conveyer belt. A first thermal treatment is performed to activate a portion of the aluminum foil and the phosphorous layer on the first surface to form an aluminum phosphide (AlP) layer. A molten silicon material is spray-coated on a second surface of the remaining aluminum foil, and a second thermal treatment is performed to make the silicon material transferring into a p-type polySi layer on the n-type AlP layer. A solar cell including the n-type AlP layer and the p-type polySi layer is formed, and the solar cell is respectively annealed and cooled down in a first and a second vertical stack.
