The application of polyphenylene ether in the photovoltaic industry is also crucial. Solar cells are the core of solar power systems, but a single solar cell can only produce 0.5-0.6 volts, which is far below the voltage required for practical use. In order to meet the actual demand, multiple solar panels must be combined into a solar cell square array via PV connectors to obtain the required voltage and current. However, PV connectors operate in harsh environments, where safety and longevity are key issues, so connectors with high reliability are needed, and polyphenylene ether is the ideal material to meet this need.
