Abstract
Methods and apparatus to control zone temperatures in a solar cell production system are disclosed. An example furnace to fire photovoltaic cells includes: a plurality of zones comprising firing elements configured to fire a metallization layer of photovoltaic cells by heating the photovoltaic cells in the zones; one or more belts configured to transport photovoltaic cells through a sequence of the plurality of zones; a user interface comprising one or more input devices; and control circuitry configured to: control the firing elements for the plurality of zones; and modify a configuration of two or more of the plurality of zones based on input received via the input device.
