The large-scale application of solar photovoltaic power generation technology will greatly increase the consumption of some rare metals. For example, the electrode preparation of crystalline silicon cells requires the consumption of silver, tellurium, indium, gallium, etc. These materials also have broad application prospects in other technical fields. If the rare metals in photovoltaic modules are not recycled after they are scrapped, it will inevitably cause waste.
According to the research of the European Union PV CYCLE organization, among the waste photovoltaic modules, glass accounts for about 70% of the total weight, aluminum accounts for about 18%, and semiconductor materials account for about 4%. In other words, most of the materials of photovoltaic modules have the possibility of recycling. Through the recycling and reuse of waste photovoltaic modules, rare metals, glass, aluminum and semiconductors can be recycled to achieve the purpose of reducing the exploitation of primary resources, reducing the energy consumption of resource extraction, and reducing the impact and damage to the ecological environment. Secondly, the recycling and reuse of waste photovoltaic modules can give birth to new industrial forms and create more employment value. From the current recycling process of waste photovoltaic modules in Europe, the entire operation and management process of waste photovoltaic module processing includes collection, registration, transportation, recycling and recycling, etc. Each link requires a large number of personnel to participate, especially the recycling link requires professional recycling technicians. Therefore, the recycling of waste photovoltaic modules can give birth to new industrial forms and create more employment value.
The road after the recycling of waste photovoltaic modules is the same as the recycling path of waste lithium batteries. It is facing the market in the form of recycled metal. The glass of waste photovoltaic panels can be removed, the frame can be disassembled, and the copper, silver and silicon metals can be separated by crushing and sorting through the battery bar.
Photovoltaic panel processing equipment Furthermore, the recycling and reuse of waste photovoltaic modules is conducive to the green development of photovoltaic integrated solutions and thus promotes the sustainable development of the solar energy industry. The new energy industry is the main connotation and important support of low-carbon development and green economy, while low-carbon development and green economy are the driving force of the new energy industry, and the two complement each other. Therefore, only by applying the waste photovoltaic panel crushing and processing equipment line to complete the link of the photovoltaic industry chain – the recycling of waste photovoltaic components, can the photovoltaic industry be green and pollution-free from source to terminal, thereby promoting the sustainable development of the solar energy industry.
