Description
Technical field
The present invention relates to photovoltaic technology field more particularly to a kind of efficient photovoltaic component systems.
Background technique
Solar battery is a kind of semiconductor devices for converting solar energy to using photovoltaic effect electric energy, is to have extensively
The clean energy resource of wealthy application prospect drops for transformation efficiency caused by protecting solar battery not influenced by natural conditions factor
It is low, it is generally encapsulated and is used for photovoltaic module, but photovoltaic module is generally influenced by " negative temperature coefficient ", is existed most suitable
Sharp-decay can occur at high temperature for operating temperature, efficiency, and generally, the short circuit current of solar battery is only with operating temperature
Rising has increased slightly, and influences less, and open-circuit voltage and fill factor are increased with temperature and be substantially reduced, such as the general silicon sun
Battery, operating temperature increase 1 DEG C, and output power reduces 0.4%-0.5%, and efficiency also declines therewith, moreover, lacking sun spoke
Photovoltaic module stops working when penetrating, and temperature decline is more, and the service life of photovoltaic module is needed vulnerable to long term high temperature difference circulating effect
By the solar radiation heat transfer in solar battery and keep certain temperature stability.
The cooling way of solar photovoltaic assembly is mainly realized by the way that heat dissipation equipment is arranged in lower plate at present, cooling skill
Art can be generally divided into passive type cooling and active cooling, and passive type cooling has higher reliability, generally takes radiating fin
The way of realization of piece, it is good between battery and radiator to thermally contact the key factor for being to maintain battery low temperature, active cooling one
As be to take away heat by flowing through the fluid in battery component rear duct, realize the cooling of battery, generally use air or water
For cooling fluid.But above method needs external heat dissipation equipment, improves solar photovoltaic assembly cost.
Summary of the invention
Based on technical problem set forth above, the application provides a kind of efficient photovoltaic component system.
A kind of efficient photovoltaic component system, including backboard, lower EVA adhesive film, solar battery, upper EVA adhesive film, glass cover
Plate, the backboard are coated with phase-change microcapsule layer close to the side of solar battery, and the phase-change microcapsule is by wall material and core material
Composition, core material be n-tetracosane hydrocarbon, and wall material is compound by modified CNTs, graphene oxide and modified titanium carbide nanometer sheet
The composite material arrived, the glass cover-plate are infrared external reflection heat-protecting glass；
Preferably, phase-change microcapsule partial size is 0.5-60 μm；
Preferably, modified CNTs is modified to obtain by CNTs through nitration mixture, highly basic, hydrogen peroxide treatment；
It is further preferred that CNTs be multi wall CNTs, tube diameters 8-15nm, 0.5-2 μm of length；
Preferably, modified titanium carbide nanometer sheet by titanium aluminum carbide after hydrofluoric acid treatment with isopropanol, ethylene glycol and trichlorine
The thermal response modification for changing iron is made；
Preferably, microcapsules press quality 100 by core material, graphene oxide, modified titanium carbide nanometer sheet, modified CNTs:
4:6:0.1 ultrasonic encapsulated in hydrochloric acid solution is made；
It is further preferred that concentration of hydrochloric acid solution is 0.01mol/L.
The technical solution that the embodiment of the present invention provides can include the following benefits:
When component temperature increases, phase-change microcapsule absorbs heat, and energy is stored in a manner of latent heat of phase change, works as component
When temperature reduces, phase-change microcapsule discharges the heat of storage, alleviates the big problem of component operation circumstance of temperature difference；Infrared external reflection every
The hot glass property of can choose penetrates visible light, and by most infrared reflection, photovoltaic module is reduced due to thermo-effect of infrared radiation
Caused by operating temperature increase, photovoltaic component system provided by the present application is combined with active cooling by passive type is cooling, holding
The temperature stability of photovoltaic module improves the efficiency of photovoltaic module.
Using n-tetracosane as phase-change microcapsule core material, modified CNTs- graphene oxide-modification titanium carbide nanometer sheet is multiple
Condensation material is wall material, is acted on by the enhanced thermal conduction of wall material, utilizes " molecular bridge " structure that core material is coated in spherical housing, phase
It is mutually cross-linked into an organically closing entirety, one side highly heat-conductive material outer room in capsule forms thermal conduction path, and enhancing is led
On the one hand thermal energy power improves the mechanical performance of capsule.
The additional aspect of the present invention and advantage will be set forth in part in the description, and will partially become from the following description
Obviously, or practice through the invention is recognized.It should be understood that above general description and following detailed description are only
Be it is exemplary and explanatory, the present invention can not be limited.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings, but the embodiment in attached drawing is not constituted to any limit of the invention
