Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Refer to shown in Fig. 2 and Fig. 3, the solar energy equipment 10 of first embodiment of the invention comprises substrate 11, solar wafer 12, snoot 16 and composite parabolic optical collector (Compound Parabolic Concentrator, CPC) 15.
Snoot 16 be arranged on substrate 11 with by solar wafer 12 around wherein, it comprises a top board 13 and four side plates 14, top board 13 and side plate 14 are combined into snoot 16 in roof mode.。
Certainly, also the first Fresnel lens 133 can be set on the first incidence surface 131, or all have the first Fresnel lens 133 on the first incidence surface 131 and the first exiting surface 132.
Certainly, the second Fresnel lens 143 also can be arranged on the second incidence surface 141, or on the second incidence surface 141 and the second exiting surface 142, the second Fresnel lens 143 is all set.
Certainly, also can on top board 13, groove be set, on side plate 14, projection be set.
Due to, top board 13 sets up into the snoot 16 of three-dimensional shape with side plate 14, thereby can collect the sunlight from each incident angle, improves the utilance of sunlight; In addition, the plate that has a concentration structure due to employing is combined into the snoot 16 of stereochemical structure, therefore, is easy to preparation, cost is lower.
Composite parabolic optical collector 15 has the first relative opening 151 and the second opening 152 and relative the first parabolic reflecting plate 153 and the second parabolic reflecting plate 154.
The size of the first opening 151 is greater than the size of the second opening 152, and the size of the second opening 152 is slightly larger than or equals the area of solar wafer 12, and the first opening 151 points to top board 13, and solar wafer 12 is positioned at the second opening 152.
