Abstract
The invention relates to semiconductor electronics and can be used for producing high-efficient broad-band electromagnetic radiation converters for directly converting incident radiation into electromotive force in both, the optically visible and optically invisible ranges. The inventive electromagnetic radiation converter comprises a semiconductor substrate with N=1 discrete local domains of a first conductivity type formed thereon, and since said substrate is of a second conductivity type, the above-mentioned domains of a first conductivity type form together with the substrate N=1 p-n junctions combined into a current node. Furthermore, isotype junctions generating repulsive isotype barriers to the minority charge carriers are formed on the face side of the substrate beyond the domains of a first conductivity type. The inventive design of the converter enables it to operate in a broader electromagnetic radiation frequency range, thereby promoting the increase in the performance factor and power thereof in comparison with converters known in the prior art, and to achieve the high accuracy and stability on the output characteristics thereof. Batteries formed of the converters of said type are also disclosed.
