Crystalline silicon solar cell production
What exactly is etching used for?
1. Dephosphorylated silica glass A layer of SiO2 containing phosphorus, also known as phosphorus silica glass, is removed before etching to prevent it from affecting the subsequent process, mainly by removing the SiO2 layer with HF. which relies on the process of HF reacting with SiO2 to form complexes.SiO2+6HF→H2SiF6+2H2O Wet acid etching Because the wafer … Read More

What you must know about polysilicon cell texturing technology
In the process of preparing crystalline silicon cells, in order to effectively improve the absorption of sunlight on the silicon surface and improve the efficiency of solar cells, it is a relatively effective process to increase the anti-reflection effect by forming uneven pits on the surface of silicon wafers. Studies have shown that the spectral … Read More
