Abstract
A photovoltaic device includes a substrate (1, 10) having a conductive electrode (2, 10), and a first semiconductor layer (3.sub.1, 11.sub.1) of a first conductivity type, a substantially intrinsic second semiconductor layer (3.sub.2, 11.sub.2) and a third semiconductor layer (3.sub.3, 11.sub.3) of the opposite conductivity type successively deposited on the conductive electrode. The hydrogen content in at least the first and second semiconductor layer (3.sub.1, 11.sub.1) is 10% or less. At least the second semiconductor layer (3.sub.2, 11.sub.2), is made of an amorphous semiconductor layer.
