Abstract

The invention relates to a dichroic mirror, which comprises a first transparent substrate, multiple layers of first dielectric films, a transparent adhesive layer, multiple layers of second dielectric film and a second transparent substrate, wherein the multiple layers of first dielectric films, the transparent adhesive layer, the multiple layers of second dielectric films and the second transparent substrate are sequentially laminated on the first transparent substrate. The section of the dichroic mirror is in the shape of parabola. The dichroic mirror is used for dividing sunlight irradiating to the second transparent substrate into light rays with different wavelength ranges, part of the light rays are reflected by the multiple layers of first dielectric films and then emitted from the second transparent substrate, and the other part of light rays are emitted from the first transparent substrate after permeating the dichroic mirror. The invention further relates to a sunlight collector and a solar energy device, the sunlight collector and the solar energy device both comprise the dichroic mirror and can collect sunlight in a wave band dividing manner, and accordingly can improve utilization rate of sunlight.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a dichroic mirror, a sunlight collecting device and a solar energy device. Background technique [0002] Because of its inexhaustible and inexhaustible advantages, sunlight is increasingly collected and utilized by humans, such as using solar cells to generate electricity. The energy of sunlight is mainly concentrated in the wavelength range of 380 to 2000 nanometers. The sensors of the existing sunlight collection devices fail to sense all the sunlight in the aforementioned wavelength bands, resulting in a large amount of sunlight not being collected and a low utilization rate of solar energy. Contents of the invention [0003] In order to improve the sunlight collection rate and maximize the use of solar energy, it is necessary to provide a dichroic mirror, a sunlight collection device and a solar energy device, which divide the sunlight spectrum into two different band...
