Abstract
The utility model relates to a building material type photovoltaic component with a novel pole leading-out mode. The building material type photovoltaic component with the novel pole leading-out mode is composed of glass, a first layer of ethylene-acetate ethylene copolymer EVA laminated film, a crystal silicon solar battery group, a second layer of EVA laminated film, a transparent TPT, a third layer of EVA laminated film, an aluminum honeycomb plate, a tin-coated belt, a bus bar and a heat-shrinkable sleeve. Crystal silicon solar battery sheets are connected in series through the tin-coated belt to form the crystal silicon solar battery group and lead positive and negative poles out through the bus bar. The building material type photovoltaic component with the novel pole leading-out mode is characterized in that the third layer of EVA laminated film, the transparent TPT, the second layer of EVA laminated film, the crystal silicon solar battery group, the first layer of EVA laminated film and the glass are laid on the aluminum honeycomb plate in turn and then are compositely lamination-molded; and the bus bar at the pole leading-out position of the crystal silicon solar battery group is sheathed with the heat-shrinkable sleeve and then leads positive and negative poles out. According to the utility model, the safety of the building material type photovoltaic component is improved; the building of a large-scale photovoltaic micro-grid is offered with a solid foundation; the technology is mature; and the operation is simple and easy.
Description
Technical field
The utility model relates to a kind of building-material-type photovoltaic component, and is particularly a kind of with the novel building materials photovoltaic component that go out utmost point mode of transparent TPT as photovoltaic component electrode insulation material.
Background technology
BIPV is the principal mode that photovoltaic power generation technology is used under construction, also is the effective way of promoting photovoltaic power generation technology in cities and towns." solar roof project " that China carries out in the recent period and " golden sun demonstration project " project are all clearly encouraged the development of BIPV.The at present installed capacity of China's building photovoltaic system has accounted for photovoltaic system total installation of generating capacity nearly 20%, the rapid growth of building photovoltaic application demand is had higher requirement to building-material-type photovoltaic component product, especially under the perfect adaptation of photovoltaic component and building, photovoltaic component security performance problem more and more receives much concern.So in the situation that photovoltaic cell is combined with building, the security performance that how to strengthen photovoltaic component has become a technical bottleneck.
Summary of the invention
The purpose of this utility model is in order to increase the insulation property of building-material-type photovoltaic component, to improve its fail safe.The encapsulating structure that adopts is: glass-EVA doubling film-crystal silicon cell group string-EVA doubling film-transparent polyvinyl fluoride composite membrane TPT-EVA doubling film-aluminum honeycomb panel encapsulates terminal box again and consists of.The tin band that is coated with at the extraction electrode place adds the cover heat-shrinkable T bush, avoids being coated with the tin band and contacts with aluminum honeycomb panel limit section, and by transparent TPT formation insulating barrier crystalline silicon power generation part and aluminum honeycomb panel electric conductor are separated.Transparent TPT has weather, ageing-resistant, resistance to tearing, good insulating properties, dimensional stability and can with the perfect characteristics such as bonding of EVA doubling film, and can effectively protect useful life of battery component.Therefore use transparent TPT as the photovoltaic component insulating material, guaranteed the security performance that member uses.The utility model mainly is applicable to building external.
The technical solution adopted in the utility model is:
The novel building-material-type photovoltaic component that goes out utmost point mode, by glass, ground floor ethylene-vinyl acetate copolymer EVA doubling film, the crystal silicon solar energy battery group, second layer EVA doubling film, transparent TPT, the 3rd layer of EVA doubling film, aluminum honeycomb panel, be coated with the tin band, the remittance bracing, heat-shrinkable T bush forms, crystal silicon solar cell sheet is connected into the crystal silicon solar energy battery group and draws both positive and negative polarity by the remittance bracing by being coated with the tin band, it is characterized in that: on aluminum honeycomb panel, lay successively the 3rd layer of EVA doubling film, transparent TPT, second layer EVA doubling film, the crystal silicon solar energy battery group, ground floor EVA doubling film, glass, carry out again composite laminated moulding, add the cover heat-shrinkable T bush on the remittance bracing that goes out utmost point position of crystal silicon solar energy battery group and draw again both positive and negative polarity, go out utmost point insulation processing.
Transparent TPT of the present utility model can form reliable and secure insulating barrier between crystal silicon solar energy battery group and aluminum honeycomb panel, heat-shrinkable T bush mainly prevents from converging bracing and contacts with limit section aluminum honeycomb panel, has realized the insulation processing of aluminum honeycomb panel and crystal silicon solar energy battery group.
The beneficial effects of the utility model are: with the insulating barrier of transparent TPT as crystal silicon solar energy battery group and aluminum honeycomb panel, and add heat-shrinkable T bush at the remittance bracing that goes out utmost point place, better improve the insulation property of crystal silicon solar cell sheet and other current-carrying part and aluminum honeycomb panel, improved the fail safe of building-material-type photovoltaic component.Provide solid foundation for building the large-sized photovoltaic microgrid, and technical maturity, simple to operation.
