Abstract
A photovoltaic device comprising at least one crystalline and one amorphous semiconductor region with different photosensitivity is provided to absorb light in a wide range of wavelength, and serves, for example, as a solar battery or a color sensor. Amorphous or microcrystalline semiconductor regions comprising those devices can be deposited easily and in a continuous manufacturing process by the use of a low temperature process, and this allows manufacture of a photovoltaic device at low cost.
