Description
Technical field
The present invention relates to a kind of solar module and heat taking method, be specifically related to the method that a kind of heat of producing when being used for the solar module opto-electronic conversion takes out, and the solar module of realizing this method.
Background technology
Along with industrial continuous development, people constantly aggravate for the consumption of conventional energy resource, such as coal, oil, the consumption of natural gas equal energy source is continuous ascendant trend, these energy all are to belong to primary energy, be non-renewable, just a little less with a bit, and growing demand causes the various energy by exhaustive exploitation, biological environment is caused the influence of very severe, and the market price of the various energy also is continuous ascendant trend, therefore, people then begin to seek various novel energies and replace original energy are such as solar energy, wind-force, the waterpower equal energy source, these novel energies all belong to regenerative resource, can reuse, and pollute for a short time, be fit to be widely used, especially solar energy is as optimal regenerative resource, obtained great attention, wherein solar cell was most widely used in the last few years.
Solar module mainly is that the basis makes with the semi-conducting material; its operation principle is that photoelectric material absorbs and the photoelectron conversion reaction to take place behind the luminous energy and produce electric current; basic structure comprises framework and is arranged at the interior modular construction of framework; described modular construction comprises the substrate (front surface of printing opacity; as glass; light-passing plastic etc.); (generally adopt resin with the transparent sealing part; as EVA glue) photo-electricity generating device (power converter unit) and back of the body sealing film (the rear surface guard block of encapsulation; as the PVF polyvinyl fluoride; TPT/TPE etc.); sunlight sees through substrate and is radiated on the photo-electricity generating device; photo-electricity generating device is an electric energy with transform light energy directly by photoelectric effect; warp and the matching used photovoltaic junction box of battery component use electric energy output back.
Yet solar cell is becoming transform light energy in the process of electric energy, is not all to convert whole luminous energy to electric energy.Mass-produced in the market solar cell is monocrystalline and polycrystalline silicon solar cell, its average efficiency is about in the of 15%, that is to say that solar cell can only convert 15% of the solar energy of incident to available electrical energy, remaining 85% all is converted into heat energy, and the Theoretical Physics limit of the conversion efficiency of the solar cell of unijunction single crystal silicon material is 25%.In the process of conversion, continuous increase along with heat energy, similar with common electronic product, if the heat energy of the generation during the electronic product running can not in time dissipate, normal operation to product will bring very big adverse effect, and also be so when showing on the battery component, can reduce the efficient of opto-electronic conversion greatly, also will damage photoelectricity simultaneously and produce device, shorten the useful life of solar cell.
For making solar module operate as normal muchly, in the prior art, outside framework, add heat abstractor, be similar to water-cooled, air cooling cooling system, by recirculated water or circulating air heat absorption, reach heat radiation.But heat energy also is the part that solar module absorbs the solar radiation energy, as if this part energy being taken out and collects, be used, but not it needing to be considered as harmful heat of dissipation, just can reach the purpose that makes full use of the energy, and widen the function of solar module.
