Abstract
Abstract A semiconductor photoelectric generator is formed of semiconductor photoelectric converters united into a solid-state matrix, each converter having the shape of a microminiature parallelepiped and containing; an alloy region; a base region; at least one P-N junction making an angle with an operating surface of the generator exposed to radiation; a metallic conductor on at least one of said regions making the same angle with the operative surface as the P-N junction and deposited all over the parallelepiped-surface uniting the parallelepipeds of the converters into a matrix; and wherein the width of a microminiature parallelepiped is approximately equal to the diffusion length of minority carriers in said base region.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
109 words
A semiconductor photoelectric generator, comprising semiconductor photo-electric converters having the shape of microminiature parallelepipeds which are united into a solidstate matrix and each of which contains: an alloy region; a base region; a P-N junction making an angle with the operating surface of the generator exposed to incident radiation; a metallic conductor on at least one of said regions, making the same angle with said operating surface of the generator and deposited all over the face of said parallelepiped, said metallic conductor interconnecting said parallelepipeds into a matrix, and the width of said microminiature parallelepiped being approximately equal to the diffusion length of minority carriers in said base region.
Claim 2
Dependent Claim
109 words
A semiconductor photoelectric generator, comprising semiconductor photo-electric converters having the shape of microminiature parallelepipeds which are united into a solidstate matrix and each of which contains: an alloy region; a base region; a P-N junction making an angle with the operating surface of the generator exposed to incident radiation; a metallic conductor on at least one of said regions, making the same angle with said operating surface of the generator and deposited all over the face of said parallelepiped, said metallic conductor interconnecting said parallelepipeds into a matrix, and the width of said microminiature parallelepiped being approximately equal to the diffusion length of minority carriers in said base region.
Claim 3
Dependent Claim
32 words
A generator, as claimed in claim 1, in which there are two additional P-N junctions united with the main P-N junction and arranged in parallel with said operating surface of the generator.
Claim 4
Dependent Claim
110 words
A generator, as claimed in claim 1, in which each photo-electric converter has an additional P-N junction parallel to the main P-N junction, and a further P-N junction uniting said main and additional P-N junctions, whose plane is parallel to those side faces of the parallelepiped which carry no P-N junction, said conductors being deposited on those faces which carry a P-N junction, and said photo-electric converters being united into a matrix by means of the conductors between said regions with the same type of conductiOn, said base regions of all said photo-electric converters having a common conductor deposited on the side opposite to said operating surface of the generator.
Claim 5
Dependent Claim
33 words
A generator, as claimed in claim 3, which has a further P-N junction which unites said main and additional P-N junctions and whose plane is parallel to said operating surface of the generator.
Claim 6
Dependent Claim
28 words
A generator, as claimed in claim 3, in which the length of the microminiature parallelepiped does not exceed the diffusion length of minority carriers in said base region.
Claim 7
Dependent Claim
28 words
A generator, as claimed in claim 4, in which the length of the microminiature parallelepiped does not exceed the diffusion length of minority carriers in said base region.
Claim 8
Dependent Claim
47 words
A generator, as claimed in claim 1, in which the P-N junction is arranged so that its planes are parallel to four or five faces of the parallelepiped, and the length of the latter does not exceed the diffusion length of minority carriers in the base region.
