Abstract:
A photovoltaic device may be provided having a semiconductor substrate, an i-type amorphous layer or an i-type amorphous layer formed over a front surface or a back surface of the semiconductor substrate, and a p-type amorphous layer or an n-type amorphous layer formed over the i-type amorphous layer or the i-type amorphous layer. The i-type amorphous layer or the i-type amorphous layer has an oxygen concentration profile in which a concentration is reduced in a step-shape from a region near an interface with the semiconductor substrate and along a thickness direction.
