Summary
Evaluation of infrared drying (at approximately 300/sup 0/C) PX-10 diffusion source in about one minute or less, revealed comparable results to the conventional oven drying at 150/sup 0/C for 15 minutes. Initially investigation of the fritted-nickel paste front contact indicated high series resistance. Series resistance was reduced upon solder dipping. Further experimentation on junction isolation by laser scribing the front edge of finished, non-AR coated, solar cells continued this period. All scribing was done in the TEM/sub 00/ laser mode. Non-AR coated cell efficiency as high as 10.4% was achieved at a laser output level of 7 watts/cm/sup 2/ and a Q-factor of 3000 pulse/inches. This performance was equivalent to non-AR coated control cells processed by back side scribing and breaking. Further evaluation of the titanium-isopropoxide base spray-on AR solution applied with the Advanced Concepts spray system located at Sensor Technology, Inc., revealed no new results. System is still plagued with problems that interfere with the atomization of the source. A new lamination lay-up procedure has been successfully demonstrated using Crane-Glas to prevent gas entrapment and aluminum foil as a vapor barrier.
