955,595. Photo-electric devices. GENERAL ELECTRIC CO. Ltd., and FERRANTI Ltd. July 11, 1961 [July 15, 1960], No. 24728/60. Heading H1K. [Also in Division G1] A semi-conductor body 1 with a PN junction is encapsulated in a transparent body 7 attached to or integral with an hemispherical lens 8. The arrangement converts solar to electrical energy. The body 1 comprises a slice out from a P-type silicon crystal with an N-type zone formed by diffusion into a major surface. Gold electrodes 2 and 3 are provided, electrode 2 being annular to provide a window through which light may fall on the junction. A brass plate 4 with a screw stem 5 provides one terminal while a soldered wire 6 provides the second terminal. The device is encapsulated in a transparent body 7 of epoxy or acrylic resin. A hemispherical lens 8, cast or machined to shape separately, is bonded to the body 7 or, since it is made of the same material as the body 7, may be cast with it in the process of encapsulation. |
