Studies of M-I-S type solar cells fabricated on silicon

Metal-insulator-semiconductor solar cells have been studied on silicon. The emphasis in this report is on M-I-S cells fabricated on n-type silicon. Results for M-S cells on this material have been poor to-date with efficiencies of only about 2% having been achieved at open circuit voltages of 0.250 volts. Using M-I-S cells on n-type silicon efficiencies of almost 9% have been obtained at open circuit voltages of better than 0.4 volts. Increase in the short circuit current has also been seen.
