Abstract: MCZ(Ge)(magnetically confined Czochralski,germanium doped) silicon wafers have been used in semiconductor industry wider and wider because of its higher mechanical intensity and frequency property.In this paper,the electrical performance of solar cells on MCZ(Ge) silicon substrates is introduced.The best BOL(begin of life) AM0 efficiency of the MCZ(Ge) BSFR solar cells is 15%,and the best BOL AM0 efficiency of MCZ(Ge) BSR solar cells is 12.3%.The 1MeV electron radiation experiment is carried for some MCZ(Ge) solar cells.For comparison,normal CZ BSFR solar cells and BSR solar cells are fabricated and tested.The electrical performance and radiation resistance of MCZ(Ge) solar cells are almost the same as those of normal CZ solar cells.

Key words: MCZ(Ge),  solar cells,  radiation resistance
