(US5277786-A)      Process comprises (a) forming a semiconductor layer on the conductive surface of a substrate, (b) forming a transparent and conductive layer on the semiconductor layer, and (c) forming a collecting electrode on the transparent layer. The process involves repairing one or more defective portions occurring at or in the semiconductor layer between steps (a) and (b) by subjecting the layer to electrodeposition processing in an electrolytic soln. contg. a charged paint or resin capable of depositing an insulating material. The conductive surface of the substrate is made the electrode for the electrodeposition. The charged paint or resin is insulating and in the form of fine particles. The electrolytic soln. pref. also contains a surfactant.    USE/ADVANTAGE -   Efficient and rapid repair of a defective portion liable to cause a short circuit in a photoelectric conversion device, without performing a detecting process.    (EP500071-B1)      (A) In the prodn. of a photoelectric conversion device by (a) forming a semiconductor layer on a conductive surface of a substrate, (b) forming a transparent conductive layer on the semiconductor layer and (c) forming a collecting electrode on the transparent layer, the novelty is that defective semiconductor layer portions are repaired between steps (a) and (b) by electrodeposition of insulating material selectively at the defective portions using the conductive surface of the substrate as an electrode.    The electrodeposition operation may comprise electrodeposition from an aq. soln. of a paint or a dispersion of a resin; electrolytic polymerisation using a soln. or dispersion of a monomer to deposit a polymer film; or electrodeposition of an oxide film from a soln. contg. an inorganic cpd.    USE/ADVANTAGE -   The processes are useful in the mfr. of solar cells, photosensors, electrophotographic photosensitive devices, flat panel displays, etc. Defective semiconductor layer portions (e.g. pinholes and hillocks causing short circuits) can be efficiently and rapidly repaired without the need for prior art defect detection processes.
