A clear valency electron controlability has been found in hydrogenated amorphous silicon carbide produced by the plasma deposition of [SiH4 (1-x) + CH4 (x)] gas mixture. A series of experimental investigation on electrical, optical and optoelectronic properties in the amorphous silicon carbide has been made. Emplying a-SiC : H as a wide gap window material in p-i-n a-Si solar cell, more than 7.5% conversion efficiency has been obtained with Jsc=13.45mA/ cm2, Voc=0.909volts and FF=0.617.
