Background technology
The volume of building is increasing at present, and people are also higher and higher to the aesthetic of building masonry wall, generally needs
Want the decorations such as construction wall.
However, the support a large amount of electric power of construction wall need of work, in the big of environmental pollution today and development of clean energy
Under environment, construction wall causes the waste of a large amount of electric power and causes environmental pollution indirectly.
Invention content
To overcome the problems in correlation technique, the application provides a kind of energy-saving luminous construction wall.
The application is achieved through the following technical solutions：
A kind of energy-saving luminous construction wall, including：One composite material wall, which is characterized in that be arranged on the wall
There are lighting device, energy storage device, control device and solar cell module；The solar cell module and the control device
Electrical connection；The control device is electrically connected with the lighting device；The control device is electrically connected with the energy storage device；It is described
Electrically connect as conducting wire connection.
Preferably, the lighting device is LED light device, realizes illumination light-emitting function.
Preferably, the solar cell module is based on dye-sensitized solar cells.
Preferably, the dye-sensitized solar cells are constituted by light anode, to electrode and electrolyte；The light anode
Structure be FTO substrates from outside to inside, the tungsten oxide nano that is grown on FTO substrate surfaces, be coated on tungsten oxide nano
The glass microballoon of bottom；The tungsten oxide nano is nucleocapsid, and core is tungsten oxide nano, and shell is titanium oxide；It is described right
Electrode is FTO substrates, reflective layer, Pt Catalytic Layer from outside to inside；Antifreezing agent normal propyl alcohol is added in the electrolyte.
Preferably, the preparation process of the dye-sensitized solar cells is as follows：
Step 1 makes FTO substrates：
A) FTO substrates are cleaned：It selects FTO electro-conductive glass as the substrate of light anode, first, cuts FTO electro-conductive glass, use
The conductive one sides of ultra-clean cloth wiping FTO for speckling with liquid detergent, remove the impurity such as greasy dirt, dust existing for surface, then use deionization
Water rinses for several times repeatedly, until liquid detergent is cleaned up, puts it into ozone clean machine, ozone treatment 10min, then according to
It is cleaned by ultrasonic 30min respectively according to the sequence of acetone, ethyl alcohol, deionized water, is dried up with nitrogen gun for use；
B) tungsten oxide nano is grown：The metal of one layer of 150nm thickness is deposited on the surfaces FTO using magnetron sputtering technology
Tungsten film grows source as tungsten oxide nano, while realizing that the localization of tungsten film is grown using ceramic template, in magnetron sputtering process
Ceramic template is attached to the surfaces FTO, wherein the pore diameter of ceramic template is 2 μm, and spacing is 50 μm, magnetron sputtering electric current
For 2A；Tungsten oxide nano growth uses thermal oxidation process, and the FTO electro-conductive glass for being coated with tungsten film is put into thermal evaporation stove,
Under the protection of inert gas, 400 DEG C keep the temperature 5h, are taken out after natural cooling；
C) nucleocapsid tungsten oxide nano is prepared：The ethanol solution for weighing 100ml, is added 1ml's
C16H36O4Ti is stirred evenly under 70 DEG C of water-baths, has the FTO electro-conductive glass of tungsten oxide nano to be put into solution growth,
11s is stood, is then quickly removed, which repeats five times, can ensure that nanowire surface adequately superscribes
Shell structure, then anneal the sample of taking-up at 400 DEG C 1h, carries nucleocapsid tungsten oxide nano after natural cooling to obtain the final product
FTO substrates；
Step 2 adsorbs glass microballoon：
The glass microballoon (Glass Bead Diameter is 5~10 μm) that 20g is bought is taken to be cleaned with deionized water, it is dry, it is added to
It is filtered by vacuum after magnetic agitation 20min in the hydrofluoric acid solution of 20mol/l, it is dry after being cleaned to neutrality with deionized water, it removes
Ionized water 100ml sequentially adds 2.5g sodium citrates, 2.2g ammonium sulfate and 5g nano silver particles, and ammonium hydroxide is then added and adjusts pH
Value is 6, and dry glass microballoon is added in above-mentioned solution, at 60 DEG C, magnetic agitation 2h, and reaction postcooling to room temperature；It will
The FTO substrates with nucleocapsid tungsten oxide nano obtained in step 1 immerse in above-mentioned solution, are stood at 80 DEG C of water-bath
5h, you can form glass microballoon combination nucleocapsid tungsten oxide nano-material in FTO substrate surfaces.
Step 3 is prepared to electrode：
The FTO electro-conductive glass for choosing size identical as light anode, then in one layer of Ag of its surface magnetic control sputtering, as reflective
Layer, Ag thickness are 300nm, and Pt catalyst layers are then deposited again, and Pt catalyst layer thickness is 50nm.
Step 4 assembles dye-sensitized solar cells：
Electrolyte applies traditional three anion electrolyte of iodine/iodine：The acetonitrile solution of 100ml is weighed first, is added thereto
Entering the lithium iodide of 0.1M, 0.1M iodines, the tetrabutylammonium iodide of 0.6M 4- tert .-butylpyridines and 0.6M is protected from light ultrasonic 5min,
So that it is fully dissolved, then weigh the nano TiO 2 nano-particle of 8g, under 70 degrees Celsius of water-bath, TiO2 nano-particles are added
In electrolyte solution, 5ml antifreezing agent normal propyl alcohols are eventually adding, ultrasonic 30min makes it be sufficiently mixed uniformly；
Dye solution：N719 powder 50mg, absolute ethyl alcohol 30ml are weighed, N719 is added in absolute ethyl alcohol, is fully dissolved,
It is protected from light stirring 12h.It takes the dye solution of above-mentioned preparation to be put into brown glass ware, FTO substrates is then entered into the brown glass
It in ware, is protected from light and is sensitized 3h at 60 DEG C, take out, be then packaged together to electrode and the light anode, encapsulating material is using heat-sealing
Film encapsulates aperture by electrolyte from the aperture injection to electrode one end, and it is quick to form improvement type dye of the invention for connecting wire
