Zusammenfassung:	Methods and apparatus to provide closed loop control in a solar cell production system are disclosed. An example solar cell production system includes: a firing furnace comprising a plurality of zones and a belt configured to transport photovoltaic cells through a sequence of the plurality of zones, the zones comprising firing elements configured to fire a metallization layer of photovoltaic cells by heating ambient air in the zones to respective temperatures; a cooling chamber configured to cool the photovoltaic cells; a photovoltaic cell tester configured to measure a property of the photovoltaic cells after cooling of the photovoltaic cells in the cooling chamber; and control circuitry configured to control firing elements based on the property of the photovoltaic cells measured by the photovoltaic cell tester.
