Abstract

The invention relates to a solar device which comprises a ceramic base plate, a plurality of III-V group solar chips, and an encapsulation body, wherein the III-V group solar chips are arranged on the ceramic base plate and are used for converting solar energy into electric energy on the ceramic base plate; and the encapsulation body covers the ceramic base plate and the III-V group solar chips, at least one Fresnel lens is formed on the position of the encapsulation body corresponding to the III-V group solar chips, and sunlight passes through the Fresnel lens and is converged on the III-V group solar chips.

Description

technical field [0001] The invention relates to a solar device and a manufacturing method thereof. Background technique [0002] With the rapid development of industry, the gradual depletion of fossil fuels and the emission of greenhouse gases have attracted worldwide attention, and the stable supply of energy has become a major global issue. [0003] Compared with traditional coal-fired, gas-fired or nuclear power generation, solar cells (solar cells) use the photoelectricity effect to directly convert solar energy into electrical energy, so there is no accompanying production of greenhouse effect gases such as carbon dioxide, nitrogen oxides, and sulfur oxides. polluting gases, and can reduce dependence on fossil fuels and provide a safe and autonomous source of electricity. [0004] The general solar cell structure is to integrate the solar chip, driving circuit, etc. on a substrate, and then weld a metal substrate on the substrate as a heat sink to guide the heat genera...
