金属コンタクトを形成する改良された方法

摘要

PROBLEM TO BE SOLVED: To provide methods of forming metal contacts by use of metal inks in manufacture of photovoltaic elements.SOLUTION: The metal inks are selectively deposited on semiconductor coatings by inkjet and aerosol apparatus. The composite is heated to selective temperatures where the metal inks burn through the coatings to form electrical contacts with the semiconductor. Metal layers are then deposited on the electrical contacts by light induced or light assisted plating.
