Abstract

A double-sided solar energy utilization device, comprising at least two double-sided reflection units. The double-sided reflection units each comprise a double-sided light energy utilization portion having double-sided light energy utilization surfaces; each light energy utilization surface is provided with a light-transmitting portion; each light-transmitting portion comprises two transmission surfaces; the two light-transmitting portions are separately arranged on two sides of the double-sided light energy utilization portion, and a tetrahedral structure is formed and used for collecting sunlight from side surfaces, achieving the effects of reducing reflection, improving an incident angle and enhancing heat dissipation, significantly improving the power generation efficiency, and prolonging the power generation time; the light-transmitting portions of the tetrahedral structure can also play a role in protecting the double-sided light energy utilization portion sandwiched therein; the transmission surfaces of the tetrahedral structure achieve the effects of transmission and refraction, and can also gather light from a light-transmitting body to a first or second light energy utilization portion by means of total reflection, so as to reutilize the light from the interior of the light-transmitting body. The plurality of double-sided reflection units can be laid side by side in a vertical, horizontal or inclined mode or the like, so that mounting and use in various different environments can be met.
