The Role of the Reduction of ITO on the Electrical Properties of the p-i Junction: A Thin SiO Layer as a Remedy
The reduction of the ITO by the deposition of an a-Si:C:H p layer by means of a Plasma Enhanced Chemical Vapour Deposition (PECVD), is considerably diminished if a thin silicon monoxide layer (estimated to be ...
