Background technology
Turn into the epoch of focus in this energy problem, not only to tap a new source of energy, also to save the existing energy.It is applied to
The energy resource consumption of building account for total worldwide energy consumption 30%-40%, these energy be mainly used in interior of building heating,
Radiating, ventilation and electrical equipment etc..In view of heat loss, window is the weak link in building.In order to improve comfort level, window face
Product is done bigger and bigger, and in some commercial buildings, the area that window is occupied is suitable with wall area, and it is to pass through to have a very big energy
Glass diffusion produces energy waste, and reduction energy consumption through window turns into the market demand.
1984, American scientist Lampert and Sweden scientist Granqvist propose it is a kind of using electrochromic film as
The novel energy saving window on basis, i.e. electrochromic (Electrochromic window, ECW), referring to " Electrochromic
Coatings for Smart Windows ", J.S.E.M.Svensson and C.G.Granqvist write,《Solar Energy
Materials and Solar Cell》,Volume 12,1985,Pages 391-402.By adjusting visible ray and near-infrared
The transmitance of light wave, is artificially selectively adjusted outdoor light to indoor amount of radiation, so as to change the temperature of interior.Its typical case
Structure as shown in Fig. 2 being superimposed transparency conducting layer, electrochromic layer, dielectric substrate and ion storage between two layers of transparent substrates
Layer, constitutes a sandwich structure.Under the driving of external voltage, when ion insertion or abjection electrochomeric films, aoxidize
Reduction reaction is so that Optical thin films change.Electrochromic layer is core layer, is the main material of modulated optical property
Material, when applying voltage, with the insertion and abjection of ion, film occurs color change, typically requires that film has good in transparent state
Good optical transmittance, and obvious color change should be showed in coloured state.Intermediate layer is ion transport layers, is mainly used to
Ion is turned on, is pure ion conductor, electrochromic layer and ion storage layer is kept apart.It is also ion storage layer to electrode layer,
There is provided and storage ion, play a part of balancing charge, the effect of transparency conducting layer is that from external circuit electronics is transferred into discoloration
In material.
When the ion in the electronics and ion transport layers of external circuit enters electrochromic layer simultaneously, when ECW is coloured, screen
Cover most of from outdoor to indoor light, indoor temperature reduction.Reversely during pressurization, electronics and ion are simultaneously from electrochromism
Layer abjection, when ECW fades, outdoor is high to indoor light radiation transmitance, improves indoor temperature, increase illumination；Relative to existing
Low-E energy-saving glass, ECW can dynamically controllable regulation it is outdoor to indoor temperature, can more reach the effect saved on demand.
But electrochromic device needs the external voltage driving of several volts to realize colour change function, it would be desirable to be able to consuming electric power.
The function of solar cell is that solar cell is converted into voltage and current, is a kind of optical-electrical converter, according to
Sill can be divided into crystal silicon solar batteries, non-crystal silicon solar cell, compound solar cell, organic semiconductor solar energy
Battery.Changed colour using the self energizing of solar powered achievable electrochromic device, without outer extra attrition voltage.1996
Bechinger reports DSSC on Nature periodicals and the optical drive of electrochromic device combination is electroluminescent
Electrochromic device (photoelectrochromic device), referring to " Photoelectrochromic windows and
Displays ", BECHINGER C etc. writes,《Nature》,Volume 383,1996,Pages 608-610.Including electrically conducting transparent
