Abstract
A solar batterycomprises a metal electrode layer, a pin junction, and a transparent electrode layerwhich are successively laminated on a substratesuch as a silicon substrate. The pin junctioncomprises an n-layer, an i-layer, and a p-layerwhich are laminated in succession. The i-layeris formed by amorphous iron silicide (FeSi:H) containing hydrogen atoms. In the i-layer, at least a part of the hydrogen atoms contained therein terminate dangling bonds of silicon atoms and/or iron atoms, so that a number of trap levels which may occur in an amorphous iron silicide film can be eliminated, whereby the i-layerexhibits a characteristic as an intrinsic semiconductor layer.
