1,206,034. Solar cells. CLEVITE CORP. 7 Feb., 1968 [17 Feb., 1967], No. 6116/68. Heading H1K. A solar cell array has a plastics base 11 on which are deposited an array of first conductors 12, then the two layers necessary to make the barrier layer cell 14, then an insulating strip 16 to protect the edges of the cells against short-circuiting by the array of second conductors 17 which may be applied as a conductor pattern formed on a plastics layer (not shown) to be used as a protective coating. The conductor arrays may be duplicated along the other edge of the row of cells to eliminate the effect of possible breaks. In another embodiment, Fig. 1 (not shown) intended for greater power output the photo-cells are deposited on to large area contacts (21) and are provided with upper contacts (24) of grid form, a tab 27 on each grid being soldered to an exposed area of an adjacent lower contact to form the series connections. An embodiment generally similar to this (Figs. 6 and 7, not shown) has the lower contacts bent up to meet the bent down upper contacts and there soldered together. As specifically described the cells have lower layers of cadmium sulphide, and have upper layers of cuprous sulphide formed by deposition from a slurry and subsequent firing, or formed by exposure of the cadmium sulphide surface to a solution of cuprous ions. Electrode materials are specified and alternative semiconductors suggested. |
