Abstract
The utility model relates to a new type of photovoltaic component with bypass structure which belongs to the solar electric power generation device. The utility model is characterized in that a bypass chip diode with customized design, as a photovoltaic component bypass diode, directly connects with the solar battery series connection group and is sealed together inside the component. The photovoltaic component sealing technology provides the solar battery with an excellent weatherability. The bypass diode of the internal bypass photovoltaic component and the single solar cell slice adopt the same connection and sealing methods which are provided with a higher reliability compared with the normal method that the connection box internally connects with the bypass diode and which simplifies the built-up connection of the photovoltaic component and increases the entire consistency of the flat photovoltaic component. The utility model is especially suitable for integrated photovoltaic application environment like photovoltaic power generation, etc. associated with construction.
Description
Technical field: the utility model relates to a kind of novel internal bypass structured light photovoltaic assembly.Belong to device of solar generating.
Background technology: because the voltage of single solar cell is lower; if protection is not easy to damage especially; during solar energy power generating is used a plurality of solar cells are carried out encapsulating after certain being connected, form photovoltaic module, can under various harsh environmental conditions, use.Conventional photovoltaic module or title solar module are made up of encapsulating material, solar battery string (also) joint group, terminal box.Several photovoltaic modulies connect and compose photovoltaic arrays by the certain way serial or parallel connection, add other auxiliary control appliance, finally form the solar power plant.
When the mutual connection in series-parallel of photovoltaic module constitutes the photovoltaic arrays use, if have one or several cell sheets to occur damaging in the square formation in some photovoltaic modulies or when being shaded, cause this assembly internal resistance to be increased, the electric current that other assembly produces this assembly of flowing through, this component faults battery sheet is equivalent to a resistance, can produce very big heat, damages solar cell sometimes, this effect is hot spot effect, and it is consumed on this fail battery sheet the part electrical power of photovoltaic arrays generation simultaneously.
Usually in the terminal box of photovoltaic module, install bypass diode additional, be connected between the positive and negative lead-in wire of photovoltaic cell parts, with the harm of minimizing hot spot effect, and the unlikely too much unnecessary consumption of electrical power that the solar cell square formation is produced.The outer connection reliability that connects bypass diode often is lower than the solar-energy photo-voltaic cell part reliability, and it can reduce system reliability; Conventional in addition diode need add encapsulation, cost is slightly high, especially in the solar energy power generating that combines with building is used, owing to require photovoltaic module organically to combine with building, for improving the flattening harmony of photovoltaic module, generally do not adopt terminal box, but electrode is drawn in the side, bypass diode is installed again, can be influenced bigger system reliability.
Summary of the invention: the purpose of this utility model is to overcome the shortcoming of prior art; invention provides a kind of and can directly be encapsulated in the photovoltaic module, with chip diode as bypass diode; this bypass diode can better be protected; reduce the unnecessary consumption of photovoltaic module electrical power when being shaded; simplify the connection of photovoltaic module, improve the Total tune of flattening photovoltaic module.
Technical solutions of the utility model are achieved in that the internal bypass photovoltaic module is made up of encapsulating material, solar battery string joint group, bypass diode (or terminal box), after wherein bypass diode (3) directly is connected in parallel with solar cell (2) string (also) joint group, together be encapsulated in photovoltaic module inside; Bypass diode (3) directly is encapsulated in component internal with solar cell (2) string (or also) joint group after directly being connected; Bypass diode (2) is a chip diode.
The utility model structural feature is to adopt chip diode as bypass diode, and bypass diode and the solar cell that needs are connected directly to be encapsulated in after being connected in the middle of the photovoltaic module, for bypass diode and connection thereof provide good protection.Be specially adapted to and build the integrated photovoltaics such as photovoltaic generation that combine and use.
Chip diode adopts and makes solar cell same type of material and similar technology manufacturing, and structural design can be satisfied the demand by the electric current of bypass.
The utility model internal bypass photovoltaic module can improve photovoltaic module bypass diode reliability, has simple in structurely, easy to use, does not need bypass diode is carried out other extra encapsulation, the advantage that weather resisteant is fabulous.The chip diode that the present invention uses directly is encapsulated in component internal with the solar battery string joint group, can well be protected, and working stability is reliable.
Description of drawings:, the utility model is further described below in conjunction with the accompanying drawing illustrated embodiment.
Fig. 1 is the structural representation of the utility model internal bypass photovoltaic module.
Embodiment: among Fig. 1, solar cell (2) is arranged on the encapsulating material of photovoltaic module (1), have bypass diode (3) and solar battery string joint group output to be in parallel on encapsulating material, (4) are the photovoltaic module electrode leads to client.When certain solar cell in the photovoltaic module breaks down and internal resistance when increasing; parallel connection is encapsulated in bypass diode (3) conducting of this photovoltaic module; the electric current that other battery sheet produces in the photovoltaic arrays is passed through from bypass diode; guarantee the power output of other assembly of photovoltaic arrays, thus the safety of protection fault solar cell.Because bypass diode is to adopt sheet, and bypass diode and connection thereof be directly to be packaged together with solar cell piece, so the reliability and stability raising.
To Crystalline Silicon PV Module, can adopt crystalline silicon sheet diode, this diode adopts conventional semiconductor technology manufacturings such as diffusion and electrode preparation.
The 1-encapsulating material; The 2-solar cell; The 3-bypass diode; 4-photovoltaic module electrode leads to client.
