We investigate amorphous silicon (a-Si: H) thin film solar cells in the n-i-p or substrate configuration that allows the use of nontransparent and flexible substrates such as metal or plastic foils such as polyethylene-naphtalate (PEN). A substrate texture is used to scatter the light at each interface, which increases the light trapping in the active layer.
