Description
Technical field
The present invention relates to a kind of coating, more particularly, it relates to a kind of building photovoltaic conversion coating, belong to
Energy-saving building coating field.
Background technology
Solar energy be one take too late, nexhaustible and do not have pollute clean energy resource.Along with whole world conventional energy resource
Becoming increasingly conspicuous and the continuous deterioration of ecological environment of potential collision hazard, forces countries in the world to develop the New Energies such as solar energy energetically
Source.In recent years, China's solar-photovoltaic technology has obtained significant progress, and requires also to step up to building energy conservation, photovoltaic
Architecture-integral (BIPV) is the perfect adaptation of photovoltaic and building, brings new direction to the development of new forms of energy.
The advantage of photovoltaic generation and Integration of building, it is obvious that one is to be not take up soil, saves space；Two be can from from
With, reduce the energy consumption during power transmission and expense；Three is cost-effective, uses New Building Materials to substitute the exterior of costliness
Exterior material, decreases the overall cost of building；Four is to use grid-connected photovoltaic system, can supply to electrical network in peak times of power consumption
Electricity, solves electrical network peak valley imbalance between supply and demand；Five is that to produce is green clean energy resource, has stopped to be brought by general fossil fuel power
Environmental pollution.At present, BIPV mainly has three kinds of installation forms, the most 1. on plane roof, pitched roof added
What sky was installed is combined mount type with roof, metope；2. the component of building element or is independently become together with combination of architectural fabric
Type, like rain shed component, sunshading board structure etc.；3. solaode and building materials are combined with each other and form the building materials of new building element
Type, such as photovoltaic curtain wall, photovoltaic window etc..In photovoltaic building installation process, should be noted that problems, as roofing, roof anti-
Water, drainage problem, the inclination angle offering question of photovoltaic module, ventilation and heat problem, dust accumulated snow problem etc..Although photovoltaic
The plurality of advantages such as architecture-integral has efficiently, economy, environmental protection, and used in the demonstration project of various places, but photovoltaic is built
Building implementation phase be also introduced into large-scale, this is owing to solar photovoltaic building integration there is also some problems, such as system
Relatively costly, cost of electricity-generating is high, system conversion ratio is the highest, solar energy power generating is unstable, is affected big etc. by weather.
The photovoltaic module being presently used for BIPV is all solar photovoltaic cell panel, and at solaode
In, 95% is above silica-based, is divided into monocrystaline silicon solar cell, multi-crystal silicon film solar battery and the amorphous silicon membrane sun
Can battery；The remaining solaode less than 5% is made up of other inorganic material, including: III V race (GaAs, InP
Deng), II VI races (CdS system) and zinc phosphide (Zn3P2) etc.；It addition, be then few by the solaode that organic material is core
Count or be in conceptual phase.The cost of manufacture of monocrystaline silicon solar cell is higher so that it can't by a large amount of extensively and
Use at large.From the point of view of polysilicon solar cell is from cost of manufacture, more cheap than monocrystaline silicon solar cell, but
The photoelectric transformation efficiency of polysilicon solar cell is the lowest, additionally, the service life of polysilicon solar cell is also than list
Crystal silicon solar batteries is short.Other photovoltaic materials are also due to numerous reason such as environmental problem, economic problems, carry out source problem etc. and difficult
With popularization and application.Meanwhile, solar panel complex manufacturing technology, cost is high, heavier-weight, and matter is hard, without bending flexibility.
Photovoltaic transition material is combined with synthetic resin, makes a kind of function with photovoltaic transfer capability for building and be coated with
Material, in the actual enforcement of BIPV, it will be a kind of novel photovoltaic building combining form.Solar energy photoelectric conversion
Coating has bending flexibility, adapts to the abnormity metope such as curved surface, folding face, and application is extensive, and it has environmental protection, dicoration simultaneously
Well, production technology is simple, cost of manufacture is cheap, raw material sources are extensive, be easily achieved the features such as industrialized production.
China Patent Publication No. CN101280131A disclose a kind of photovoltaic coating converting the solar into electric energy and
Its preparation method, this invention utilizes quasiconductor conductivity principle, by crystalline silicon grind after with firming agent, solvent, synthetic resin according to
Proportioning prepare, be made as positive level A component coating and as bear level B component coating, then by A component coating and B
Component coating layered coated separates with synthetic resin layer between object top layer, A, B component coating and connects with electrode outlet line respectively
Connecing, under sunlight irradiates, coating can form electric potential difference in PN ties, and provides electric energy.But this invention photovoltaic conversion coating is led
The poorest, electron transfer difficulty, internal resistance is big；Owing to not being external wall or roofing special coating, its coating matrix resin resists
Dirt is poor, long-term outdoor environment, and dirty fouling is necessarily received on coating top layer, and light transmission declines, and photovoltaic conversion efficiency reduces；Sunlight
Utilization rate is low, and photovoltaic conversion efficiency is relatively low.
Therefore, a kind of electric conductivity is good, and internal resistance is low, dirt-resistant self-cleaning, has the environment protection architecture solar photoelectric of practicality
Conversion coating is significant to the enforcement of BIPV.
