Monocrystalline silicon solar cell production involves growing high-purity silicon ingots via Czochralski method (99. 999% purity), slicing into 180-200μm wafers, texturing with NaOH/KOH solution (reducing reflectivity to <10%), doping via phosphorus diffusion (900°C, 30min) .

The key is performance on cloudy days: when irradiance is below 500W/m², monocrystalline silicon's generating efficiency is 8% higher than polycrystalline silicon – Sichuan has 60 cloudy/rainy days per year, so monocrystalline silicon generates an extra 150,000 kWh.
