Heterojunction crystalline silicon solar cells using nanocrystalline cubic silicon carbide emitter

Heterojunction crystalline silicon solar cells using a hydrogenated nanocrystalline cubic silicon carbide emitter has been developed. The use of the widegap emitter significantly reduced the optical absorption loss in the emitter region. The solar cells also showed high open circuit voltage of above 0.718 V. This high open circuit voltage indicates that the recombination velocity at the interface of crystalline silicon/hydrogenated nanocrystalline cubic silicon carbide emitter is quite low.
