Technical field
This utility model relates to a kind of BIPV component, a kind of building integrated member based on CIGS flexible thin film photovoltaic.
Background technology
Solar energy is as a kind of new forms of energy, and safety and environmental protection is renewable, is referred to as optimal new forms of energy, within about 40 minutes, is radiated at tellurian solar energy, it is sufficient to for the consumption of 1 year energy of global human;Solar electrical energy generation is gradually promoted as a kind of new generation mode.
But there is certain limitation in the mounting structure of tradition solar electrical energy generation:
1, tradition device of solar generating is arranged separately in surface, soil, top, house.In face of land resource the most in short supply, particularly around increasing megalopolis, build solar power station kind of waste beyond doubt on earth's surface;And the building up of more and more high buildings and large mansions so that it is more and more less that roof area amasss accounting at house facade.
2, the plate-like structure of tradition solar power generation cell limits its utilization rate, and this flat generating pond also is not suitable for being arranged on the curved surface exterior wall of existing high building.When panel faces south, solar energy is excessively concentrated, and produces substantial amounts of heat while producing electric energy, output can be caused to lose, as photovoltaic cell is had a negative impact and shortens the actual life of solaode by thermal cycle impact because of overheated;Face to face during backboard sun, luminous energy turns electric energy efficiency and is remarkably decreased and even lost efficacy.
Utility model content
Goal of the invention of the present utility model is: the platy structure that there is tradition solar power generation cell for prior art limits its utilization rate and the tradition irrational problem of device of solar generating mounting arrangement, it is provided that a kind of building integrated member based on CIGS flexible thin film photovoltaic.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of building integrated member based on CIGS (Chinese name: CIGS) flexible thin film photovoltaic, this component at least includes basal layer and photovoltaic module layer, described photovoltaic module layer is connected to substrate surface, and described substrate surface bends and has curvature α, and its value is more than 0.
Existing plate armature is not suitable for the construction requirement of BIPV;Basal layer and CIGS flexible thin film photovoltaic's component layer connected mode that this utility model comprises are flexible, can fasten by local stiffness, can consolidate by EVA (Chinese name: ethylene-vinyl acetate copolymer) gluing, plate-like structure relative to tradition solar power generation cell, this utility model can bend, assembles, splice, and is adapted to the BIPV component various curved surface exterior walls in installation process.
Preferably, the surface that basal layer contacts with described photovoltaic module layer (1) includes that several bending units, the curvature of each described bending unit are β, curvature β of wherein said bending unit > α.
Preferably, described basal layer is conductive metal material basal layer.
Preferably, described basal layer is aluminum basal layer.
Preferably, described basal layer is provided with radiating component away from the surface of described photovoltaic module layer.
Preferably, described basal layer includes splicing several basal layer unit on described photovoltaic module layer, has gap between adjacent two described basal layer unit.
Preferably, the surface area summation that described basal layer contacts with described photovoltaic module layer is less than the following table area of described photovoltaic module layer, and its ratio is 5% to 95%.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
1, this utility model is relative to the plate-like structure of tradition solar power generation cell, it is possible to bends, assemble, splice, is adapted to the BIPV component various curved surface exterior walls in installation process, and disclosure satisfy that more building element outward appearance demand;Device of solar generating not being confined to roof, whole building surface all as the carrier of building integrated member based on CIGS flexible thin film photovoltaic, thus can considerably increase light-receiving area, increasing electricity output;And guide the two-dimensional plane layout that conventional photovoltaic generates electricity into three-dimensional space layout, the situation that relative remission land resource is in short supply.
2, increase light-receiving area, while raising light turns electrical efficiency, have benefited from rational heat dissipation design, the heat of generation is taken away, output will be caused to lose because of overheated, also because of thermal cycle impact, photovoltaic cell will not be had a negative impact, thus extend the actual life of photovoltaic cell.
