Neutron transmutation doped silicon solar cells
Neutron transmutation doping has been used to introduce a precisely controlled and extremely uniform concentration of phosphorus into single crystal and polycrystalline silicon. Experimental solar cells have been made from neutron transmutation doped (NTD) single crystal silicon, and from NTD polycrystalline silicon rods, in which the grains range in size from a few microns to several hundred microns. Between the limits of 3 x 10/sup 13/ P cm/sup -3/ to 2 x 10/sup 15/ P cm/sup -3/, the extent of the work so far with polycrystalline silicon, the ratio of polycrystalline to single crystal open circuit voltage runs from about 0.85 to 0.9; short circuit current from 0.75 to 0.6; maximum power from 0.7 to 0.6; and the fill factor ratios are about unity.
