NOVELTY - Article (I) comprises one or more polymeric precursor compounds for copper-silver-indium-gallium-aluminum-sulfur/selenium, silver-indium-gallium-aluminum-sulfur/selenium or copper-indium-gallium-aluminum-sulfur/selenium deposited onto a substrate (10).    USE - (I) is useful in photovoltaic device (claimed) to convert light into electrical energy. (I) is useful for making semiconductor and optoelectronic materials including copper-silver-indium-gallium-aluminum-sulfur/selenium absorber layers for solar cells, and devices including thin film and band gap materials for photovoltaic applications including devices and systems for energy conversion and solar cells.    ADVANTAGE - (I): is stable; allows a control of the stoichiometry, structure and ratios of atoms in the semiconductors, preferably metal atoms; prepares chemically and physically uniform semiconductor layers; makes solar cells and other products at relatively low temperatures; exhibits enhanced processability to form a thin film for making solar cell; provides enhanced control of the uniformity and properties of a semiconductor material; enhanced solubility in organic solvents; and makes photovoltaic layers, semiconductors, and devices regardless of the morphology, architecture, or manner of fabrication of the semiconductors or devices.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) a deposition system for making (I), comprising a spray apparatus, a printing apparatus, an electrodepositing apparatus, a coating apparatus, a liquid deposition apparatus and/or a spin casting apparatus; and    (2) making (I), comprising (a) providing the polymeric precursor compounds or one or more inks containing the polymeric precursor compounds, (b) providing the substrate and (c) depositing the compounds or inks onto the substrate.
