A New Method of Metallization for Silicon Solar Cells

By: Nasa, National Aeronautics and Space Adm

A low cost ohmic contact on silicon solar cells based on molybdenum-tin metal systems was developed. The approach is based on the formulation of a screenable ink composed from molybdenum oxide and tin mixture. The reduction of Mo03 into Mo and the establishment of Mo 03: Sn ratio is studied. Both tasks were done in an experimental station constructed for this purpose. The results show that molybdenum was formed from its oxide at 800 C. and improved in bonding to silicon at 900 C. A 20% Mo03-80%Sn mixture was converted into metallic coating within this temperature range. Macha, M. Unspecified Center NASA-CR-158603, DOE/JPL-955318-79/1, QR-1 JPL-95531
