Solar power generation has completed the transition from "policy-driven" to "economic-driven": the mass production efficiency of perovskite stacked cells has reached 30%, the decline in silicon material prices has driven system costs to drop by another 10%, and BIPV and photovoltaic hydrogen production have opened up a 100 billion incremental scenario. China continues to dominate the market with the world's largest and most complete industrial chain, but high-proportion grid-connected consumption, European and American carbon tariffs and anti-dumping investigations are still short-term constraints. It is expected that the global installed capacity will grow by no less than 15% from 2025 to 2030. In 2030, the perovskite production capacity will reach 161 GW, and the cost of photovoltaic storage will drop to 0.25 yuan. Photovoltaics will officially become the world's main energy source.
