Abstract
A method of producing a photovoltaic device includes providing a stretchable substrate for the photovoltaic device; and stretching the substrate to produce a stretched substrate. The method further includes depositing a structure comprising hydrogenated amorphous silicon onto the stretched substrate; and subjecting the deposited hydrogenated amorphous silicon structure and the stretched substrate to a compressive force to form a compressively strained photovoltaic device.
