Abstract

The invention discloses a condensation combination system based on a minitype gallium arsenide photovoltaic cell. The condensation combination system based on the minitype gallium arsenide photovoltaic cell is mainly composed of a condenser and a secondary optical element. The condenser preferentially comprises a toughened glass substrate and an organic silica gel aspherical planoconvex lens. The secondary optical element preferentially comprises a spherical lens made of optical glass. The working process of the system comprises the steps that the aspherical planoconvex lens converge parallel sunlight to the surface of the secondary optical element, and the secondary optical element again converges and transmits the sunlight to the surface of a minitype photovoltaic cell chip. The condensation combination system based on the minitype gallium arsenide photovoltaic cell is simple in structure, strong in practical applicability, and capable of improving optical efficiency of a traditional main condenser based on the Fresnel lens, reducing machining difficulty of condensers, improving acceptance angles of concentrating photovoltaic modules, improving allowance tolerability of machining and installation of concentrating photovoltaic modules, improving evenness of focusing facula, and improving conversion efficiency of solar cells.
