High Purity Ammonium Hydroxide (29%) for Solar Cell Manufacturing EG
Doping process in solar cell manufacturing. Quality improvement with high-purity ammonia water.
In the solar cell manufacturing industry, minimizing the contamination of impurities during the silicon wafer doping process is a crucial factor that affects the efficiency and performance of solar cells. High-purity ammonia water is essential to enhance the uniformity and reproducibility of the doping treatment. Using ammonia water with a high level of impurities can lead to variations in doping effects and degradation of the wafer surface quality, potentially resulting in decreased performance of the final product. Our Electronic Grade ammonia water from India employs a super-pure water production process using RO + DM treatment, achieving impurity removal at the ppm to ppb level. We ensure strict quality control in the doping process to support the manufacturing of high-performance solar cells. [Usage Scenarios] - Doping process of silicon wafers - Manufacturing of solar cell modules [Benefits of Implementation] - Improved uniformity of doping treatment - Enhanced performance of solar cell modules - Improved yield
