no. 1 approach

[0028] The optical element of the first embodiment is composed of a material that is transparent to light. The optical element includes a surface, a back surface opposed to the surface, and a connection surface. The surface has a concave surface in a region facing the connection surface. The point closest to the connecting surface is regarded as the closest point, and there is a first special point outside the closest point. Below, use Figure 1 to Figure 5 The first embodiment will be described. Hereinafter, as long as it is not specifically denied, it is assumed that the connection element 1 is a solar cell, that is, a light-receiving type, and a case where the light incident on the optical element 15 is introduced to the connection element 1 will be described. When the connecting element 1 is a light-emitting type, the light is emitted from the optical element 15, so the light path is opposite to that of the light-receiving type. The description of the embodiment in which ...

no. 2 approach

[0057] Figure 5 A schematic cross-sectional view of the optical element 15 constituting the optical device of the second embodiment is shown in FIG. image 3 with Figure 5 The difference is that Figure 5 The first surface 8A is a convex curved surface. With the refraction of the convex curved surface, the optical element 15 can be further thinned.

no. 3 approach

[0059] Image 6 And Figure 7 The schematic sectional view of the optical device of the third embodiment is shown. The heat transfer body 14 may be provided with screws 16. The screw 16 makes it easy to fix the heat transfer body 14 to the optical element 15. Here, the heat transfer body 14 is an external thread, and the central hole 6 of the optical element 15 is an internal thread.

Abstract

An optical element of an embodiment includes an optical element made of a material transparent to light, the optical element including: a back surface facing the front surface; and a connection surface. The front surface includes a recessed surface in a region facing the connection surface. The recessed surface has a point closest to the connection surface as a closest point, and has a first singular point other than the closest point.

Description

Technical field [0001] The embodiment relates to an optical element and an optical device. Background technique [0002] The cost of the average concentrating area of ​​the solar cell may be reduced due to the combination with an inexpensive concentrator. The condenser is one of the optical elements. Such a device that combines a concentrator and a solar cell is called a concentrating solar cell. In addition, when considering the installation space and weight constraints, it is desirable that the condenser be as thin as possible. [0003] As a technique for realizing the above-mentioned expectations, there is a type called RXI (Refraction (R), refleXtion (X), and total Internal reflection (I)) type condenser. Compared with the conventional CPC (Compound Parabolic Concentrator: Compound Parabolic Concentrator) type, this concentrator is characterized by being very thin. [0004] The above-mentioned concentrator is described in relation to solar cells. However, the above-mentioned...
