Description
Technical field
The present invention relates to technical field of thin-film solar, relate in particular to a kind of integrated Thinfilm solar cell assembly, it has the characteristic of low-e characteristic and thin-film solar cells concurrently.
Background technology
In recent years solar cell industry development is swift and violent, and along with the continuous reduction of cost, solar cell just progressively enters among people's the life, plays a greater and greater role.Thin-film solar cells is a kind of in the solar cell, it adopts the only thin-film material realization photoelectric conversion of hundreds of nano thickness, main feature is: material usage is few, be convenient in deposition on glass, can produce translucent effect, low light level power generation performance is good, the high temperature power generation performance is good, the comprehensive electric generating ability is strong etc., current wide development space is arranged.
At present, thin-film solar cells mainly is divided into silicon-based film solar cells, cadmium telluride diaphragm solar battery and copper-indium-galliun-selenium film solar cell, and their main distinction is that the photoelectric conversion layer material therefor of core is different.But the basic structure of battery all adopts identical three-decker, and ground floor is take the layer of transparent conductive film as front electrode, and the second layer is the photoelectric conversion thin layer of core, and the 3rd layer is the back electrode thin layer that conductive metallic material or its composite material consist of.
For thin-film solar cells, an important purposes is to be made into the BIPV(BIPV) Thinfilm solar cell assembly.For building curtain wall and window applications, the BIPV assembly is made as translucent assembly usually, possesses certain light transmission.Make translucent BIPV Thinfilm solar cell assembly, normally adopt intensive horizontal laser light to carve the light penetrating slit crack, attenuate photoelectric conversion thin layer thickness, and the way that adopts transparency conductive electrode alternative metals back electrode.
Present BIPV Thinfilm solar cell assembly primary structure is: be followed successively by from top to bottom glass, transparent conductive film, photoelectric conversion thin layer, back electrode, PVB glued membrane, glass.Its glass is generally toughened glass, to guarantee fail safe.And the PVB glued membrane is high as a kind of reliability, has the material of excellent adhering, has replaced traditional E VA glued membrane and has used in BIPV.But the BIPV Thinfilm solar cell assembly only possesses generating capacity, and heat-insulating capability is relatively poor, like this when using building curtain wall or window-glass, the sunlight heat can pass to indoorly from outdoor, if hot summer, temperature within doors will be unusually high, in order to reduce inner temperature of room, can only increase the use amount of air-conditioning, energy consumption is increased, be unfavorable for energy-saving and emission-reduction.
In order to address the above problem, there is the technical staff to design a kind of novel Thinfilm solar cell assembly, it is combination film solar cell and low-e glass, so that completely cut off heat when utilizing solar power generation.For example, Chinese patent literature CN101510567A discloses a kind of " being applied in architectural solar film battery assembly ", it is comprised of electropane layer, hull cell layer, aluminum membranous layer, EVA layer, float glass layer and double glazing layer from top to bottom successively, two ends between float glass layer and double glazing layer are respectively equipped with spacer bar, spacer bar separates cavity of formation with float glass layer and double glazing layer, and the side in the upper and lower sides of cavity is provided with the LOW-E rete; The terminal box with diode is equipped with in spacer bar outside to the corresponding float glass layer side therein; Draw respectively an electrode on electropane layer and the aluminum membranous layer, two extraction electrodes are connected with circuit in the terminal box.
This solar film battery assembly has following defective:
1, this battery component only simply will consist of hollow structure between common BIPV Thinfilm solar cell assembly and the low-e glass, solar power generation is combined with the low-e performance, need in use to carry out packaging technology and the low-e double glazing preparation technology of loaded down with trivial details thin-film solar cells, increased manufacturing and assembly difficulty;
2, light transmission is poor, owing to adopted the EVA adhesive film, and be provided with two-layer electro-conductive glass at the low-e double glazing, and so that its light transmission reduces;
3, adopted the EVA glued membrane, EVA glued membrane easily jaundice is aging, and is poor to the adhesive property after the glass fragmentation faced simultaneously so that battery component is not attractive in appearance, has potential safety hazard;
4, adopt tin indium oxide as the conductive film layer of electro-conductive glass, when being coated on the glass baseplate owing to indium tin oxide films, complex process causes manufacturing cost high, simultaneously because the price of indium is high and supply is limited, so that material cost is also very high.
