What is the recycling process of solar cells? What is the investment income of solar cell recycling?

The energy industry has been undergoing fundamental changes, and the gradual transformation of renewable energy procurement is obvious. However, not all sustainable things will maintain this state at the end of their life cycle. At least that is about photovoltaic (PV) solar panels, the most common concern.

They are sustainable energy, depending on the sun radiation, and can power our housing. However, what happens if the solar panel cannot effectively function? Explore their journey during the recovery process in the following info: How long can the solar panel use life? Most people think about the problem when considering solar panels. According to the research, the service life of solar panels is about 30 years.

In the life of the photovoltaic panel, the power capacity may be reduced by 20%. Between the initial 10 to 12 years, the maximum decline in efficiency is 10%, while the efficiency drop rate in 25 years is 20%. These numbers are guaranteed by most manufacturers.

Despite this, experience shows that in fact, efficiency fell by 6% to 8% after 25 years. Therefore, the service life of the solar panel may be longer than the official regulations. High-quality photovoltaic panels can even reach 30 to 40 years, although the efficacy is lowered, it can still work properly.

The disposal of the solar panel is seen from the perspective of regulations, solar cell panel waste is still classified in general waste. The only exception is in the EU level, in which the photovoltaic panel is defined as an electronic waste in the electrical and electronic equipment waste (WEEE) instructions. Therefore, in addition to other legal frameworks, the directive also regulates the water management of photovoltaic board.

Solar battery manufacturers are constrained by law. When the technology of recycling solar panels begins to appear, they must meet specific legal requirements and recycling standards to ensure that the solar panels will not cause the environment. Solar plate waste is actually, if the recycling process is not carried out, by 2050, there will be 60 million tons of solar battery panel waste buried.

Since all solar cells contain a certain amount of toxic substance, this will truly become a unusual sustainable energy procurement method. Therefore, people generally think that solar panels are not recycling is a myth. However, this is a process that requires time to implement, and further research is needed to achieve all the potential to fully recover all solar panel components.

Therefore, the design unit and the recycling unit are necessary to closely cooperate, so that the recycling capacity can be guaranteed by the useful ecological design. Solar panel recycling processes have two main types of solar panels that require different recovery methods. These two types: silicon groups and thin film bases can be recycled using different industrial flows.

At present, the silicon-based panel is more common, but this does not mean that the material of the thin film battery is not very valuable. Research on the topics of solar panel recycling, many technologies have already been produced. Some of these technologies have even reached an amazing 96%, but the future goal is to increase the standard to higher.

The recovery process of the silicon-based solar panel recovered silicon-based photovoltaic plate is first to disassemble the actual product as aluminum and glass components. Almost all (95%) glass can be reused, while all external metal components are used to re-formulate the battery frame. The rest of the material is treated in a thermal processing apparatus of 500 ¡ã C to reduce the binding between battery elements.

Due to extreme high temperature, encapsulating plastic evaporation, allowing the silicon battery to be further processed. Supporting technology ensures that these plastics will not be wasted, so it is reused as a heat source for further heat treatment. After heat treatment, green hardware is physically separated.

80% of them can be easily reused, while the remaining is further refined. Silicon particles known as silicon wafers are extracted. After the fragmentation silicon is melted, it is used to manufacture a new silicon module, thereby reaching the recovery of silicon materials to 85%.

Compared with the film-based solar panel recovery, the method of processing based on the film is more intense. The first step is to put them in a shredder. Then, use a hammer to ensure that all particles do not exceed 4-5 mm, which is the size of the laminated layer to keep the internal material, so it can be removed.

Contrary to silicon-based photovoltaic plates, the remaining substance consists of solids and liquid materials. In order to isolate these substances, use a rotating screw which basically causes the solid portion to rotate in the tube, and the liquid drops into a container. Liquid passes through precipitation and dehydration to ensure purity.

The resulting material should be made of metal, completely separated different semiconductor materials. The latter step depends on the actual technique when the production panel, however, an average 95% semiconductor material is reused. The solid substance is contaminated by the so-called intermediate layer material, and the quality of these materials is lighter, and can be removed by the vibrating surface.

Finally, the material must also rinse. Leaved pure glass, saving 90% of glass elements, easy to manufacture. Solar Waste Management Future Income, since we know that solar panels can be recycled, then the problem is what other benefits have brought for the economy (if any).

Obviously, it is necessary to establish a suitable solar panel recycling infrastructure to manage a large number of photovoltaic components that will be disposed in the near future. Once it is in place, we will witness some positive factors and new opportunities in the economy. By 2050, photovoltaic recovery will not only create more green jobs, but also recycled about 11 billion pounds.

A large amount of influx will make the production of 2 billion new panels, without investing raw materials. This means that only about 630GW can be generated by repeating the previously used materials. Due to the continued decline in solar prices, more and more families and enterprises choose to invest in solar power systems.

As a result, more economic opportunities will appear in the solar cell recovery department.
