Targeting the research and mass production of organic, thin-film, and third-generation high-efficiency solar cells, we provide high-purity functional materials ranging from gram to ton levels in the laboratory, helping to shorten process validation cycles, reduce amplification risks, and quickly achieve high conversion efficiency and long lifespan. High purity and low impurities: Metal impurities<10 ppm, moisture<100 ppm, ensuring low defect density of perovskite films. Strong process compatibility: solution, vapor deposition, slit coating, inkjet printing, R2R have all been verified and passed. Flexible customization: We can provide a specialized formula for low-temperature flexible substrates (PET/PI curing at ≤ 120 ° C).
