(US4786607-A)      Semiconductor device is made by firstly forming a first electrode on a substrate. A rectifying semiconductor layer (I) is then formed on the electrode. A photocurable resin (II) is applied over layer (I) to fill defects of layer (II) with the resin.    The resin (II) is irradiated to render portions of it, inside the defect, insol. and the remaining portion, soluble to a solvent. The soluble portion of (II) is removed with the solvent. A second electrode is formed on layer (II). Finally, any remaining defects are burnt out, forming short-current paths, by applying a reverse voltage between the first and second electrodes, less than the breakdown voltage of layer (I).    ADVANTAGE -   Adverse short circuits are eliminated. (13pp)3    (US4812415-A)      In mfr. of a semiconductor device, partic. photovoltaic device, a tramsparent electrode (2) is formed and patterned on a substrate and semiconductor layer (3) is formed on the electrode, a number of gaps and pinholes (6,6') being unintentionally produced. The layer is coated with a photocurable resin to fill the holes (7,7'). The semiconductor layer is irradiated from the glass substrate side, selectively curing the resin in the holes. Uncured resin is then removed and mfr. of the device is continued.    ADVANTAGE -   Adverse short circuits due to defects are eliminated. (11pp)t    (US4937651-A)      A semiconductor device comprises (a) a first electrode formed on a substrate, (b) a rectifying semiconductor layer on the 1st electrode, large defects of the semiconductor layer being filled with a resin and small defects, smaller than the large defects and filled with resin, and an insulator disposed between the 2nd resin and the rectifying layer, and (c) a 2nd electrode formed on the semiconductor layer. Short circuiting between the 1st and 2nd electrodes is minimised to (i) the resin which fills the large defects and (ii) the insulator disposed in the small defects.    USE/ADVANTAGE -   In photovoltaic devices. Short circuits and shunts due to pin holes or other gaps produced in the mfr. are eliminated. The procedure is simple. (13pp)o    (US5089426-A)      A solar cell formed from multiple photoconversion devices connected in series. Each device comprising an upper and lower electrode with a central photosensitive layer. The cell is produced by applying a lower electrode pattern onto a substrate surface and then covering the substrate and the electrode with a photosensitive layer. Defects in the insulating layer are filled with an insulating material. A laser is used to pattern the semiconductor layer and to give grooves through the semiconductor layer with access to the lower electrode pattern. After removing the scribing residues by etching the upper electrode pattern is applied to provide connections to each device.    ADVANTAGE -   Relatively large devices can be formed in a simple way with a reduced risk of short-circuits. (13pp)
