Light guide element and solar cell module

Abstract

The invention discloses a light guide element and a solar cell module. The light guide element is placed on the edge of the solar cell assembly. A first gap is formed between the outer edge of an edge solar cell and the inner edge of a frame. The light guide element includes a plane of emission, a plane of incidence and a plane of reflection. The plane of emission receives incident light entering the first gap, and refracted light is selected from the following paths after the incident light enters the light guide element: path 1, the refracted light is emitted from the plane of emission to the edge solar cell; path 2, the refracted light is reflected on the plane of reflection and then emitted to the edge solar cell; and path 3, the refracted light is reflected by the plane of reflection at least once to the plane of incidence and then is emitted to the edge solar cell after at least one total reflection is performed by the plane of incidence. Through the light guide element, light emitted to the gaps in the solar cell assembly can be guided to the solar cells, so the utilization rate of sunlight can be improved.

Description

technical field [0001] The invention relates to a light guide element and a solar cell assembly, in particular to a light guide element and a solar cell assembly capable of improving the utilization rate of sunlight. Background technique [0002] In order to obtain greater output power, multiple solar cell modules are usually used in combination. refer to figure 1 and figure 2 , each solar cell module 1 includes a plurality of solar cells 11 and a frame 12 for fixing, the front of the solar cells 11 is covered with a protective glass 13 for protecting the battery, and the frame 12 for fixing the solar cells 11 Integration with protective glass 13 (refer to figure 2 , the protective glass 13 is covered on the solar battery sheet 11, and the frame 12 buckles the solar battery sheet 11 and the protective glass 13, and the frame mentioned here refers to the frame structure of the solar battery module), thereby forming the solar battery module 1. [0003] In actual use, whe...
