655 mV open-circuit voltage, 17.6% efficient silicon MIS solar cells

Abstract

Major new results are reported for silicon MIS solar cells. Open-circuit voltages up to 655 mV (AM0, 25 °C) have been obtained for 0.1-Ω cm silicon wafers, substantially higher than previously reported for any other silicon solar cell. On an active-area basis, the efficiency of these high-output-voltage cells is close to the best silicon cell yet produced with 17.6% active-area efficiency (AM1, 28 °C) for a 3-cm2 cell.
