Plate type photovoltaic battery light augmentor based on micro-prism structure

The invention provides a flat-plate type photovoltaic battery light beam enhancer based on a micro-prism structure. The light beam enhancer consists of a transparent optical flat plate, the upper surface thereof is a plane which is used as an incident plane (part 1), and the bottom surface thereof consists of a plurality of continuous micro-prism structures (part 3) and is coated with a high-reflection film, therefore, the light beam incident on the incident plane of the structure at different angles is collected by an optical flat plate (part 2), transmitted to an emergent plane (part 4) and irradiates on the surface of the photovoltaic battery (part 5), thus realizing the reinforcing of the light beam received by the photovoltaic battery. The structure can effectively improve the efficiency of the photovoltaic battery.
