<p>A process of making a photovoltaic unit includes steps of simultaneously forming a first layer of n-type material and a second layer of p-type material using a continuous casting process, and continuously bonding the first and second layers to form a p-n junction. The process may be performed using a twin-roll type continuous casting system having a continuous casting mold that includes a first mold compartment for receiving molten n-type material and a second mold compartment for receiving molten p-type material. The molten n-type material and the molten p-type material are gradually solidified into semi-solid shells and are pressed together by opposed casting rolls, creating a metallurgical bond between the n- type material and the p-type material that forms an effective p-n junction. The process permits the large scale efficient manufacturing of photovoltaic units.</p> |
