PHOTOCONVERTER OF CONCENTRATED SOLAR RADIATION Russian patent published in 1995 - IPC

FIELD: conversion of solar energy to electric one. SUBSTANCE: photoconverter of concentrated solar radiation has solar cell with contact grid and buses on exposed surface put on base in cooled case with branch pipes to feed heat transfer agent and protective glass. Buses on exposed side are provided with back-up plates of additional current collecting buses. Collector with hollow electrode is common for back-up plates. Layer of porous copper is arranged between solar cell and base, collector has inclined reflecting surfaces. Base with seal divide case into two independent spaces. There are made holes in solar cell, base and case bottom through which hollow electrode passes electrically insulated from them and heat transfer agent. Space above solar cell and hollow electrode are filled with dielectric heat transfer agent and luminophor. Base at point of sealing contacts conductive case and part of hollow electrode between case bottom and current lead-out bus is fabricated in the form of bellows. On base there can be arranged battery of solar cells, collectors of back-up plates can be placed in spaces between them. All collectors integrated in common electric circuit with hollow electrode. EFFECT: improved operational efficiency. 2 cl, 4 dwg
