The production of a semiconductor by the glow discharge decomposition of a silane type gas is accomplished advantageously by a method which comprises effecting the glow discharge decomposition of introduced silane type gas with a plurality of opposed electrodes disposed substantially perpendicularly to a substrate and insulated from the ground potential and subsequently allowing the product of the decomposition to be deposited on the substrate disposed so as to be exposed to the introduced silane type gas. The semiconductor obtained by this method is free from the drawbacks suffered by the conventional method using a power source of high frequency.

摘要:
A photovoltaic device including a plurality of amorphous silicon unit cells each having a p-i-n structure layered in succession on a substrate made of stainless steel. A transparent electrically conductive layer, for withdrawing a photoelectromotive force in cooperation with the electrically conductive substrate, is formed on the uppermost unit cell, so that rays of light may be incident upon the photovoltaic device from the uppermost unit cell. Preferably, the thickness of the unit cells closer to the light incidence surface is selected to be less than the thickness of the unit cells farther from the light incident surface. Each of the unit cells is structured such that the n type, i type and p type layers are disposed in the above described order from the light incidence surface in terms of the impurity type.
