Description
Technical field
The present invention relates to the utilization of solar energy, is the device of electric energy and heat energy with conversion of solar energy, relates to utilizing the blind pipe light penetrating device with the device of solar energy converting for electric energy and heat energy.
Background technology
The application technology of solar energy maturation is the low-temperature water heating utilization of solar energy, main employing vacuum glass Manifold technology is a heat energy with conversion of solar energy, technical at this kind, there is employing that heat pipe is inserted into glass tube with vacuum inside with the technology of heat transferred to outside acquisition solar energy, and on the vacuum glass basis, further improve and the various devices of exploitation, wherein being provided with vacuum layer in the glass tube with vacuum is incubated, in the inside of vacuum layer selective coating is set solar energy is absorbed conversion, though the vacuum glass layer has well been realized insulation, selective coating has well been realized sun transformation of energy, but, heat energy utilization after it transforms gets up very uneconomical, as adopt existing method that water is fed directly to glass tube with vacuum inside and directly carry out heat exchange, but to winter just can't use, realized heat transfer in the winter time though adopt hot pipe technique, but increased cost, reduced the utilance of heat energy, present this technology is applied to the hot water of low temperature and uses, and can't realize the application of the middle high temperature of solar energy, as the application of solar generator;
The generation technology of high temperature in the existing technology solar energy mainly is to adopt tower, slot type, and butterfly, and groove type solar is business-like solar energy photothermal converter spare, outside main the employing is not glass tube, inside is the stainless steel metal pipe, and inside vacuumizes, and realizes the collection of solar energy; But this kind absorber price height has only the enterprise of minority can grasp its production technology; The main difficult technical of butterfly solar energy and tower type solar application simultaneously also is photo-thermal conversion solar energy switching device, tower type solar particularly, need carry out work in the interval of 600-1500 degree mainly due to photothermal converter, because stable work when metal device that high temperature adopted can't be grown, thereby tower solar power station just can't be long-term carry out work, thereby need the solar energy photothermal converter spare of high temperature be improved.
Development along with the solar energy mirror technology, can adopt common optical frames or Fresnel optical frames that solar energy is collected, but, after having the solar energy mirror technology that solar energy is collected, very high density of heat flow rate will be produced, adopt common heat-transfer matcrial conversion can't realize the transmission of the heat energy of high heat flux, thereby need a kind of novel material to realize that heatproof is with efficient.
Existing solar photoelectric light-heat switching device is monocrystalline silicon, polysilicon and hull cell three major types type, on a kind of metal of plane, nonmetallic planar substrates, process a kind of solar photoelectric light-heat conversion coating, with solar energy converting is electric energy, planar substrates can be crooked film and become hull cell, coating mainly sample monocrystalline silicon, to the amorphous silicon battery of crystal silicon and film.But silicon material for solar cells can not satisfy the needs of photovoltaic industry development mostly from the outer product of semiconductor silicon material and the material end to end of monocrystalline silicon at present.Silicon materials constitute the part that is difficult to reduction in the crystal silicon solar battery component cost just simultaneously, therefore in order to adapt to the needs of solar cell high efficiency, low cost, large-scale production development, the most effective way is not adopt by silicon raw material, silicon ingot, the silicon chip process route to solar cell, and adopts directly by the process route of raw material to solar cell.In principle, a few μ m are thick just can to absorb most energy, but the thickness of actual polysilicon membrane generally is 50 μ m.Just because of this, people have developed thin film solar cell, and the filming of solar cell is to be purpose to reduce ground with solar cell cost of manufacture and the semi-conductor cell structural material of saving costliness.For from mechanical strength upper support battery thin film active layer, just need substrate.Certainly, backing material also should be cheap.So in most example, substrate is not a semi-conducting material.The semiconductive thin film that forms on substrate is a polycrystal or noncrystal, and needs not to be monocrystal.Semiconductive thin film on the substrate can form by all means: physics with growth method chemistry and substrate impregnating method in the fused semiconductor material.The transformational structure of hull cell is the same with the structure of single crystal battery, and p-n junction type, Schottky type, MIS type and heterojunction type etc. are arranged.
But the battery of existing solar photoelectric light-heat conversion, solar photoelectric light-heat converting material processing is externally increased encapsulation such as glass after on the backing material, simultaneously owing to there is not further temperature control device, make photovoltaic cell in use be subjected to Temperature Influence, the generating efficiency of common battery at noon the time reduces on the contrary, if increase the cost that attemperating unit has increased solar panel again, can not realize simultaneously the photovoltaic and photothermal comprehensive utilization, only solar panel can be gathered electric energy, an energy and heat energy can not be provided simultaneously, influence the comprehensive utilization ratio of solar energy.
