Description
Technical field
The present invention relates to improve photovoltaic cell light path simultaneously in conjunction with the method for Photo-thermal technology application, can be widely used in photovoltaic/photo-thermal assembling sphere.
Background technology
Exhaustion day by day along with non-renewable energy resources such as oil, coals, cause in the constantly soaring and < < Kyoto Protocol > > of the price such as oil, coal in recent years to anthropogenic carbon dioxide emissions quantitative limitation ，Ge state all the research and development novel energy of effort utilize the problem of aspect.
In numerous new forms of energy, the widest with the distribution of solar energy, environmental protection the most, and be the inexhaustible energy.Current Application of Solar Energy is mainly Photo-thermal technology application and photovoltaic application, yet both split type application have all caused energy source use efficiency low, utilizes the drawback of disperseing.According to authentic data, show, simple solar thermal utilization rate is 28%, and simple photovoltaic utilance is 18%.Wherein in photovoltaic generation process, there is a large amount of heat energy not to be utilized, caused efficiency of energy utilization not high.
The research of photovoltaic/photo-thermal comprehensive utilization at present becomes a focus of current Application of Solar Energy, although the related invention of some integrated application, wherein in the majority with separation application, solar energy utilization ratio is not greatly improved.
Summary of the invention
The object of the invention is to overcome above problem, by improving the light path of high permeability photovoltaic cell, increase substantially the generating capacity of photovoltaic cell, simultaneously in conjunction with the principle of solar thermal utilization by unemployed luminous energy again with the form utilization of photo-thermal, reach the object that improves solar energy utilization ratio.
For this reason, the embodiment of the present invention provides a kind of raising photovoltaic cell light path simultaneously in conjunction with Photo-thermal technology application device.This photovoltaic/photo-thermal composite generating set comprises thermal-collecting tube, high permeability photovoltaic cell, reflective mirror.
Thermal-collecting tube described in the embodiment of the present invention, is characterized in that adopting frivolous and pressure high-temp resistant material, adopts the design of traditional photo-thermal generation heat-collecting pipe.
High permeability photovoltaic cell described in the embodiment of the present invention, is characterized in that the luminous energy transmitance to not absorbed by photovoltaic cell is high, frivolous can be crooked.
Reflective mirror described in the embodiment of the present invention, it is characterized in that can reflected sunlight, and less to the sink effect of sunlight.
The income effect of type of the present invention.
The present invention adopts the pattern of photovoltaic/photo-thermal comprehensive utilization, contains photovoltaic generation, photo-thermal power generation.Take this kind of mode repeatedly to absorb luminous energy, can increase substantially the utilance of luminous energy.And the waste heat after the generating of photo-thermal power generation facility can be periphery resident heating.
Integrated structure adopts the mode settled date of single-shaft-rotation, reduces the cost of settled date facility.Luminous energy comes and goes in high permeability photovoltaic cell, has increased light path and has improved the absorption to luminous energy.Installation can be with reference to traditional slot type photo-thermal power generation principle, and the low simple installation of cost, can also can large-scalely install in small-sized installation, is widely used.
