NOVELTY - The photovoltaic modules stacked on substrate (110), includes semiconductor layers between two conductive layers. The semiconductor layers comprise cadmium based material, polymer, nanoparticle and organic composite materials, and amorphous material, and define junction at interface between semiconductor layers. One of junctions is configured to convert one spectral portion of optical energy into electrical voltage, and transmit another spectral portion to another one of junctions that is configured to convert transmitted spectral portion into electrical voltage.    USE - Spectrally adaptive multi-junction photovoltaic thin-film device.    ADVANTAGE - The spectrally adaptive multi junction photovoltaic thin-film device is facilitated with the ability to efficiently and economically convert the electro-magnetic energy in the form of light into electrical energy in the form of electrical current. The large volume production and widespread usage of photovoltaic devices, can be ensured. The conducting layers are covered with a patterned grid of highly conductive metal, so that the electrical resistance of the corresponding contact layers is decreased without substantial decrease in optical transmissivity of the corresponding contact layers. The substrate is configured provide a textured and non-uniform pattern for all junction layers, so that light scattering and absorption by junction layers can be increased. The electrical contact pair from the junction layer is connected to an individual electrical grid, so that conversion efficiency of the photovoltaic film can be improved.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for manufacturing spectrally adaptive photovoltaic device.
