Nicole Kuepper, an Australian Scientist, is only 23 years-old and she has figured out a relatively simple process that uses mostly common materials to make a low cost solar cell! In basic terms she coats a silicon wafer with something like nail polish, then prints a high resolution pattern in a modified inkjet printer on the silicon wafer with a solvent that dissolves the “nail polish”, much like acetone. The canals created from the solvent are then metalized with aluminum, and baked in an oven like a pizza, and there you have it genius in simplicity! With the proper funding this process can be commercialized by 2013 or sooner. Ms Kuepper said that the solar cells should be of high enough quality to be used anywhere in the world, including her native Australia.
