Abstract
A wafer precursor for creating photovoltaic (PV) concentrator modules and a method for fabricating solar concentrator modules using the wafer precursor. The method includes providing a crystalline silicon wafer substrate that can be used to make multiple concentrator cells to be incorporated into concentrator modules. The method also includes applying fingers as horizontal grid lines onto the crystalline silicon wafer substrate. The method also includes applying bus bars onto the crystalline silicon wafer substrate to form separate top grid structures. The number of separate top grid structures is at least two when the concentrator module is part of an optical system that has a concentration ratio of between about 8 and about 16 times sunlight. The number of top grid structures is at least three when the concentrator module is part of an optical system that has a concentration ratio of between about 17 and about 50.
