Zusammenfassung:	A CONVEYOR (102) ASSEMBLY (100) FOR USE IN A VAPOR DEPOSITION APPARATUS (60) WHEREIN A SUBLIMED SOURCE MATERIAL IS DEPOSITED AS A THIN FILM ON A PHOTOVOLTAIC (PV) MODULE SUBSTRATE. THE ASSEMBLY INCLUDES A CONVEYOR (102) MOVABLE IN AN ENDLESS LOOP PATH THAT INCLUDES AN UPPER LEG THAT MOVES IN A CONVEYANCE DIRECTION TO CARRY A SUBSTRATE THROUGH A DEPOSITION AREA OF THE VAPOR DEPOSITION APPARATUS (60). A HEAT SOURCE (118) IS DISPOSED RELATIVE TO THE ENDLESS LOOP PATH SO AS TO HEAT THE CONVEYOR (102) AT A LOCATION GENERALLY AFTER THE POINT WHERE SUBSTRATES LEAVE THE CONVEYOR (102). THE HEAT SOURCE (118) HEATS THE CONVEYOR (102) TO A TEMPERATURE EFFECTIVE FOR SUBLIMATING SOURCE MATERIAL FROM THE CONVEYOR (102). A COLD TRAP (122) IS DISPOSED RELATIVE TO THE ENDLESS LOOP PATH DOWNSTREAM OF THE HEAT SOURCE (118) IN A DIRECTION OF MOVEMENT OF THE CONVEYOR (102) AND IS MAINTAINED AT A TEMPERATURE EFFECTIVE FOR CAUSING SUBLIMATED SOURCE MATERIAL GENERATED FROM HEATING THE CONVEYOR (102) TO PLATE OUT ONTO A COLLECTION MEMBER (130) CONFIGURED WITH THE COLD TRAP (122). AN ASSOCIATED PROCESS FOR RECLAMATION OF SOURCE MATERIAL FROM CONVEYOR (102) COMPONENTS IS ALSO PROVIDED.
