Abstract:

Isolation IR heat lamp module and method of firing multi-zone IR furnaces for solar cell processing comprising lamps disposed in individual parallel channels in a reflector/insulator body to provide a cooling air channel surrounding each tube; the channels are covered with IR-transmissive plate material to isolate each lamp from adjacent lamps and the process zone. Cooling air is exhausted and recycled upstream for energy conservation. Lamp spacing can be varied and power to each lamp individually controlled to provide infinite control of temperature profile in each heating zone. For a spike zone, and in combination with downstream quench control and annealing zones, steep heating and cooling curves with very short dwell (sharp) peak temperature profiles permit faster throughput due to operation of the lampsm at essentially 100% rated capacity, at a 2× or greater heating and throughput rate without compromising lamp life, while producing solar cells with improved output efficiency.
