China has a history of more than 60 years since the first silicon single crystal, and the installed capacity of renewable energy power generation in 2023 has exceeded 1.4 billion kilowatts, accounting for more than 50% of the total installed capacity of power generation in the country and nearly 40% of the total installed capacity of renewable energy power generation in the world. At present, China's photovoltaic market has formed a complete upper, middle and downstream industrial chain, the upstream is mainly the production of polysilicon materials, the midstream includes the manufacturing of solar cells and the packaging of photovoltaic modules, and the downstream is the integration and installation of photovoltaic application systems, including the construction and operation of photovoltaic power stations.
