Recycling and reusing waste solar photovoltaic panels can give rise to new industrial forms
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...
