The invention provides a method of manufacturing a light-gathering device. The method comprises the following steps of forming a light incidence part on a translucent plate and equipping multiple projecting structure on the light incidence part, wherein, the upper surface area of each projecting area is smaller than the area of the part where the projecting structure is connected with the light incidence part; making auxiliary connecting plates connected with the upper surfaces of the projecting structures in a bonding way; heating the multiple projecting structures; drawing the projecting structures into multiple light transmission channels by exerting drawing force on the auxiliary connecting plates; removing the auxiliary connecting plates and exposing the end faces of the light transmission channels. Correspondingly, the invention provides a light-gathering device. The light-gathering device provided in the invention has the advantages of good light-gathering effects, small volume, simple structure, low cost, flexible use, simple production technology and easy manufacture.
Description
Technical field [0001] The invention relates to the field of optics, in particular to a light concentrating device and a manufacturing method thereof. Background technique [0002] Solar energy is clean and pollution-free, has huge reserves, and can be used sustainably. It is an important renewable energy source. Solar concentrating photovoltaic power generation technology uses optical concentrating components to increase the light energy density incident on the surface of solar cells, which can reduce the use area of expensive solar cells in the power generation system, and can greatly improve the overall conversion efficiency of the system, which is to reduce power generation costs, An effective way to improve power generation efficiency, and solar concentrators are one of the important components of concentrating photovoltaic power generation systems, and it is also one of the research hotspots in the field of solar energy applications. [0003] Currently, the concentrators u...
