Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the gaps between the solar cell components and the gap between the solar cell sheets and the frame in the prior art when the solar cell components are used in combination, so that the incidence into multiple gaps The defect that sunlight cannot be utilized, provides a light guide element and a solar cell assembly, and improves the utilization rate of sunlight by guiding the light incident into the gap into the solar cell sheet, thereby improving the working efficiency of the solar cell assembly

Embodiment 1

[0136] refer to Figure 4 , the gap between the two dotted lines is the first gap 101 and the width 102 of the frame, the light beam incident to the gap enters the light guide element from the incident surface 51, and directly exits from the outgoing surface 53 to the battery sheet through refraction.

Embodiment 2

[0138] refer to Figure 5 , the two dotted lines still represent the gap formed by the width of the first gap and the frame, and the incident light perpendicular to the gap enters the incident surface for divergent refraction, and then is reflected by the reflective surface and exits from the outgoing surface to the solar cell sheet.

Embodiment 3

[0140] The principle of embodiment 3 is basically the same as that of embodiment 2, the only difference is that it is not vertical incidence, refer to Figure 6 , the incident light obliquely incident to the gap enters the incident surface for divergent refraction, and then is reflected by the reflective surface and exits from the outgoing surface to the solar cell sheet.

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...
