As the fastest-growing economy in the world, China's technology and applications in the field of photovoltaic power generation are only at the downstream level of the world. The main reason is that the domestic polysilicon purification technology required for solar photovoltaic cells has not yet been mastered. This technology is currently monopolized by large foreign companies, so the cost of producing solar photovoltaic cells in China is high. The cost of photovoltaic power generation is several times the cost of general power generation, and as a result, it cannot be widely used.
