Example 2
China is a big country for producing and applying photovoltaic modules, the photovoltaic modules produced in China only in 2017 are over 60gw, and the total mass of the photovoltaic modules is over 456 million tons after the photovoltaic modules are scrapped according to the conversion of 7.6 million tons/gw.
Most of materials of the photovoltaic module are recyclable materials, recycling of the photovoltaic module is achieved, resources can be saved, exploitation of primary resources is reduced, energy consumption of resource extraction is reduced, and accordingly influence and damage to the ecological environment are reduced.
The photovoltaic module comprises 70% of glass (weight ratio, the same below), 18% of an aluminum frame, 4% of a silicon material, 0.15% of noble metal, 0.85% of a junction box, 1% of a back plate and 6% of eva.
When the waste photovoltaic module is recycled, the module needs to be disassembled, and the aluminum frame, the glass and the junction box are partially removed to obtain the silicon wafer. The effective whole silicon wafer recovery methods are the "inorganic acid dissolution method" and the "heat treatment method". Among them, the latter is classified into a "fixed vessel heat treatment method" and a "fluidized bed reactor heat treatment method".
1) Inorganic acid dissolution method
Dissolving out eva with mixed acid of nitric acid and nitrogen peroxide under certain temperature condition for a period of time, and classifying with glass. The process can maintain the integrity of the wafer, but requires further processing of the wafer.
2) Fixed container heat treatment process
And (3) putting the photovoltaic module into an incinerator, and setting the reaction temperature to 600 ℃ for incineration. After the incineration is completed, the battery, the glass, the frame and the like are manually separated. The recovered materials enter corresponding recovery procedures, and the plastic materials are completely incinerated.
3) Fluidized bed reactor heat treatment process
And (4) carrying out heat treatment on the waste photovoltaic module by using a fluidized bed reactor. The fine sand is put into a fluidized bed reactor, and under the action of air with certain temperature and flow rate, the fine sand is in a scalding flowing state and has the physical properties of liquid. The assembly is placed in a fluidized bed, the eva and backsheet materials are vaporized in the reactor, and the exhaust gases from the reactor enter a secondary combustion chamber as a heat source for the reactor. For the battery piece with the thickness of more than 400 microns, the intact silicon piece can be recycled. Because the manufacturing technology is continuously developed, the cell slice is gradually thinned, and the heat treatment method cannot obtain a perfect silicon slice, the method can only be applied to the recovery of silicon materials.
In addition to the above 3 methods, "organic acid dissolution method" and "physical separation method";
4) Organic acid dissolving method
Swelling the eva with an organic solvent to achieve the purpose of separating the cell sheet, the eva, the glass and the back sheet. The method needs long time, and about 7 days is a reaction period. In addition, the method is still in the laboratory research stage because the battery pieces are broken after eva swelling and there is a problem in organic waste liquid treatment.
5) Physical separation method
Firstly, dismantling an aluminum frame and a junction box of the assembly, then crushing the frameless assembly, separating a tin-coated welding strip from glass particles, grinding the rest part, and obtaining metal, silicon powder, backboard particles and eva particles by using an electrostatic separation method. The method finally obtains a mixture of different materials, cannot realize the full separation of single components, and is still in a laboratory research stage.
According to the technical method and experience of the existing scrapped photovoltaic module at home and abroad, the method comprises the following steps:
dissolving inorganic acid and organic acid: only for the removal and separation of eva, the removal of the bezel and the reuse of the silicon wafer are not considered. And a large amount of chemical reagents are needed, and the remaining waste liquid also belongs to dangerous waste. The method is neither economical nor environmentally friendly.
A heat treatment method: the disposal process generates a large amount of organic waste gas, and the method is neither economical nor environment-friendly.
Physical separation method: not perfect enough to separate the individual components.
Therefore, an environment-friendly and economic method for disassembling the scrapped photovoltaic module is sought, the recovery rate can be improved, the breakage rate is reduced in the disassembling process, and the national expected index is met, so that the method is very necessary.
Photovoltaic power generation principle: the sun light irradiates on the semiconductor p-n junction to form a new hole-electron pair, under the action of an electric field built in the p-n junction, holes flow from the n region to the p region, electrons flow from the p region to the n region, and current is formed after a circuit is switched on.
The manufacturing process of various technical routes is different, taking the current mainstream monocrystalline silicon PERC battery manufacturing flow as an example, the process from a silicon wafer to a battery piece is summarized as follows:
1. texturing: the surface of the silicon wafer is rough, and the reflectivity is reduced
2. Diffusion: brushing a layer of phosphor to form a PN junction (the technology content of the step is high)
3. Etching and edge insulation: removing PN junction on side surface to prevent short circuit
4. Back passivation: this is the most important step of the PERC cell, and the back passivation reduces the light transmission, thereby improving the photoelectric conversion rate.
5. Film coating: the silicon nitride film reduces reflection and protects the battery from corrosion.
6. Silk-screen printing: printed metal electrode
7. And (3) sintering: sintered electrode and silicon wafer
8. Sorting: sorting batteries of different efficiencies
The photovoltaic module comprises the following components:
photovoltaic glass: the battery piece is protected from being corroded, and the service life of the battery piece is prolonged.
EVA adhesive film: and bonding the cell with the photovoltaic glass, and bonding the cell with the back film.
Back film: insulating, dampproof, ultraviolet resistant, airtight, ageing-resistant, corrosion-resistant.
Frame: and protecting the assembly and connecting and installing.
A junction box: and leading out the bus bar.
A photovoltaic module: the photovoltaic module is based on a minimally-indivisible photovoltaic cell assembly with encapsulation and inter-connection for cell integration, and capable of providing direct current output alone. The photovoltaic module is used as a minimum effective power generation unit, bears the function of photoelectric conversion in a photovoltaic power station, and is a core part in a photovoltaic power generation system.
