摘要:
One embodiment is directed to an apparatus comprising a firing furnace comprising a heating chamber configured to fire a metallization layer of photovoltaic devices and a cooling chamber configured to cool the photovoltaic devices that have been heated by the heating chamber. The cooling chamber comprises lights to light anneal the photovoltaic devices to reduce light induced degradation as the photovoltaic devices are cooled in the cooling chamber. The cooling chamber of the firing furnace is configured to use residual heat from heating performed in the heating chamber of the firing furnace as heat for the light annealing of the photovoltaic devices. Light annealing is not performed in the heating chamber of the firing furnace.
