Abstract
A system for vapor deposition of a thin film layer on photovoltaic (PV) module substrates includes a system for cool-down of the vacuum chamber through which substrates are conveyed in a vapor deposition process. The cool-down system is configured with the vacuum chamber to recirculate a cooling gas through the vacuum chamber and through an external heat exchanger in a closed cool-down loop. An associated method for forced cool-down of the vacuum chamber is also provided.
