A spin coater is used in the production of the solar cell itself. The silicon wafer gets a drop of phophene then the wafer is spun to spread the phosphene evenly over the wafer. The wafer is then sent through the diffusion furnace to set the phosphene. This creates the P-N Junction that is the "Diode".

The wafer then gets "printed" with the conductive paste, then passed through dryng ovens. Finally it gets laser scored to provide separation of the top and bottom sides of wafer. Now the cell can generate power from sun.

The wafer then gets tagged, rated and performance matched to other cells. Those cells get laid up into a panel and covered in poly urethane.

Well that's how the process was when I worked at BP Solar.
