The fabrication of this solar cell design comprises these general steps: a. Surface preparation by cleaning and texturing to minimize light reflection. b. Diffusing an n-type dopant into the p-type wafer to form a pn junction. Back passivation through a BSF formed by Al diffusion.
Hence, the gettering process further purifies the silicon wafer. This gives room for using lower quality (and lower cost) silicon material to fabricate the wafers, knowing that they will be further purified during the solar cell fabrication.
Constant-source and constant-dose diffusion are the most common in silicon solar cell fabrication. Typical processes to form the pn junction in silicon solar cells comprise two steps: A pre-deposition process with a constant source, such as process A defined previously, to introduce the desired dose of dopant impurities in the wafer surface.
