Abstract
The invention provides an improvement on Efficient Concentrating Solar Photoelectric Converter patent, and suggests that a concentrating optical system in the patent and a spectral spitting system are merged into a special Fresnel lens so as to further reduce the manufacturing cost of a solar power generation system. A spectral solar photoelectric converter is characterized in that: solar rays are concentrated by special design through a Fresnel lens made of a high-chromatism material and split into high-energy spectral beams; and the spectral beams are irradiated on a novel photoelectric cell, the photoelectric cell consists of a group of efficient photosensitive quantum wells just matched with the solar spectral beams projected thereon in energy band difference and geometrical shape, and the photoelectric conversion quantum efficiency of the photosensitive quantum wells can reach over 90 percent. The quantum wells are skillfully connected in series and parallel to realize match of branched current so as to realize extremely high photoelectric conversion rate.
Description
Technical field
The high efficiency solar energy photoelectric transducer.
Background technology
This patent is by the artificial a kind of improvement that further reduces the cost of this patent system and make of the invention of " a kind of high-efficiency concentrating solar photoelectric converter " patent.
Summary of the invention
A kind of spectral solar photoelectric converter.
Description of drawings
Fig. 1: the structure principle chart of a kind of implementation of the spectral solar photo-translating system that this patent proposes.
Fig. 2: the structure chart of the described novel multijunction solar cell of this patent.
Embodiment
This patent can be realized with discrete optics and photo-electric conversion element, also can optical system and optical-electrical converter be integrated realization with certain transparent optical material.The various implementations of this patent be referred to as technology side by.For example, the solar cell that uses in this patent, the photoelectric sensor of all right intercropping sun tracker in certain time slice.The technical scheme that derives from thus, as long as its photoelectricity transform mode conforms to this patent, a kind of technology that should regard this patent as realizes.
The detailed description and the relative theory figure of this patent below will be provided.
As shown in Figure 1, one vertically injects sunray 1 through custom-designed asymmetric one-dimensional Fresnel lens 2 (the zigzag lens that dotted line enclosed) by solar tracking system.Among the little curved surface of each of Fresnel Lenses 2 such as Fig. 13 and 4 (little sawtooth) will fall thereon light focusing and split into the spectrum bundle, project the surface of photocell 5 then.Fresnel Lenses 2 is to be made than inhaling the ripple less material greatly to aberration monotone variation 1800 nanometers in 300 nanometers by a kind of.In fact the little curved surface of each of Fresnel Lenses 2 focuses on diverse location with the light of different colours.Therefore, objective function of optimization design is: make the focal plane of each little curved surface overlap and just cover photocell; Put the energy loss minimum that makes transmitted light more before this.Because photocell structure is asymmetric, because the yardstick of each little curved surface should not surpass photronic yardstick, this has just determined the asymmetry of Fresnel Lenses again.
Photocell as shown in Figure 2 comprises the linear array 6 of a quantum well.They are that element by 3 to 5 families in the periodic table of elements constitutes, has different can being with and differs from and by certain insulating material 7, for example, silicon dioxide or germanium dioxide separate.Whole array is produced on substrate 8, for example, and silicon or germanium, on.Use and more be with the quantum well array manufacturing photocell of difference between 0,69 electronvolt to 4.01 electronvolt, thereby just can make it better and the day spectrum higher conversion efficiency of acquisition that is complementary.In addition, can also be by the connection in series-parallel of quantum well (comprising the quantum well between the different photocells) being realized the optimum Match of photocell group of branches electric current, this can improve the generating efficiency of whole solar energy system equally.
