Abstract
THIS PROJECT ADDRESSES IMPROVEMENTS IN EFFICIENCY OF CELLS FORMED FROM PRESENT-DAY SHEET SILICON MATERIALS. SUCH IMPROVEMENT MAY BE ACHIEVED THROUGH PASSIVATION OF RECOMBINATION CENTERS THAT RESULT FROM IMPURITIES, GRAIN BOUNDARIES, AND OTHER CRYSTAL DEFECTS. IN THIS INVESTIGATION, THE FEASIBILITY OF PASSIVATION OF THESE CENTERS WITH LI AND H WILL BE ADDRESSED. LI CAN BE USED TO PASSIVATE RADIATION DAMAGE IN SPACE CELLS MADE FROM FLOAT ZONE SILICON, AND H HAS BEEN USED TO ACHIEVE PASSIVATION IN POLYCRYSTALLINE CELLS. IN PHASE I OF THIS PROJECT, THE FEASIBILITY OF APPLYING LI TO SHEET MATERIALS WILL BE EXAMINED. PHASE I ALSO ADDRESSES THE THE FEASIBILITY OF COMBINING LI AND H TO GAIN ADDITIONAL IMPROVEMENT. APPLICATION OF SUCH A PROCESS TO A VARIETY OF PRESENT-DAY SHEET MATERIALS WILL BE INVESTIGATED. IF FEASIBLE, PHASE II WILL ATTEMPT TO OPTIMIZE THE PASSIVATION PROCESS AND TO DEVELOP PRODUCTION-COMPATIBLE PROCESS TECHNIQUES. IN PHASE III, PRODUCTION EQUIPMENT FOR SHEET SILICON PASSIVATION WILL BE DEVELOPED. COMMERCIALIZATION WILL COMPRISE THE SALE OF THIS EQUIP- MENT TO MANUFACTURERS OF SILICON SOLAR CELLS.
