Summary

An experimental investigation for the wide gap window material in the amorphous silicon solar cell is shown on methane based and ethylene based a-SiC:H. The methane based a-SiC:H/a-Si:H heterojunction solar cell shows a larger short-circuit current density than the ethylene based one. From IR absorption analysis, methane based a-SiC:H film is recognized a rather ideal amorphous SiC alloy as compared with ethylene based one. It has been found through these investigations that the chemical bonding structure is an important factor for a window material. 8% efficiency barrier has been firstly broken through with this methane based a-SiC:H/a-Si:H heterojunction solar cell.
