NOVELTY - A deposition system for use with a substrate (50) comprises a solution deposition apparatus (60); a heating chamber; and at least one assembly for holding solution over the substrate to allow for a depth of at least about 0.5 microns to greater than or equal to 10 mm. The substrate comprises of a flexible material. The system includes multiple zones at different temperatures. A movable seal system defines a volume over which fluid is held over the substrate. The movable seal system uses seals that move at the same rate as the substrate in a continuous process.    USE - As deposition system for use with a substrate (claimed); as liquid system for forming photovoltaic devices; for roll-to-roll, in-line processing equipments; in solar cells; and in batch manufacturing processes.    ADVANTAGE - The system is an improved junction partner deposition system that can be prepared by using smaller amounts of starting material; and are not susceptible to imperfections in the underlying substrate that causes non-uniform deposition of junction partner material over a wide web.    DETAILED DESCRIPTION - A deposition system for use with a substrate (50) comprises a solution deposition apparatus (60); a heating chamber; and at least one assembly for holding solution over the substrate to allow for a depth of at least about 0.5 microns to greater than or equal to 10 mm. The substrate comprises of a flexible material. The system includes multiple zones at different temperatures. A movable seal system defines a volume over which fluid is held over the substrate. The movable seal system uses seals that move at the same rate as the substrate in a continuous process. The substrate is heated from ambient to about 60-90 degrees C but the solution is at a still higher temperature. The substrate comprises of a metal foil. The solution comprises precursor for forming a junction partner for a group IB-IIIA-VIA absorber layer or a precursor for forming a Group IIB-VIA junction partner or a precursor for forming a junction partner selected from cadmium sulfide (CdS), zinc sulfide (ZnS), zinc hydroxide and zinc selenide (ZnSe). The solution comprises of a Group IIB ionic species which is obtained from an aqueous solution of at least one of sulfate, acetate, bromide, fluoride, chloride, iodide, hydroxide, nitrate, oxalate, citrate, phosphate, tungstate, or hydrates of the Group IIB species; or comprises a Group VIA ionic species which is obtained from an aqueous solution of at least one of oxides, halides, sulfates, nitrates or ureates of the Group VIA species. The solution has a pH of 9-14 (preferably 11-12).    DESCRIPTION OF DRAWING(S) - The figure shows schematic view junction partner deposition system.
