  • Method of flexible photovoltaic device manufacture
    Patent number: 5232860
    Abstract: A method of flexible photovoltaic device manufacture in which an inorganic separation layer and inorganic first protective film layer are formed on a supporting substrate. On the inorganic first protective film, a first electrode, an amorphous silicon photovoltaic layer, a second electrode, and a second protective film are formed in that order. Then the supporting substrate and the inorganic separation layer are separated. The inorganic separation layer is a material that bonds weakly with both the supporting substrate and the inorganic first protective film.
