PERC modules decay by 2%-2.5% in the first year and 0.45%-0.55% year by year. N-type modules decay by 1% in the first year and 0.40% year by year.
Higher quality N-type sun panel and double glass panel
Solar crystalline silicon cells are divided into N-type sun panel cells and P-type cells according to the properties of the silicon wafer. The difference between P-type batteries and N-type sun panel batteries lies in the different raw material silicon wafers and battery preparation technology. P-type silicon wafers are made of silicon material doped with boron element, and N-type sun panel silicon wafers are made of silicon material doped with phosphorus element.
The raw material of P-type battery is P-type silicon wafer. The main preparation technology includes traditional Al-BSF (aluminum back field) and the PERC technology that has emerged in recent years. The raw material of N-type double glass panel battery is N-type double glass panel silicon wafer. The main preparation technology includes TOPCon, HJT, PERT/PERL, IBC, etc.
P-type batteries only need to diffuse one kind of impurity, so the cost is low, but the minority carrier life is short and the conversion efficiency is low. N-type double glass panel batteries have long minority carrier life and high conversion efficiency. The difficulty lies in the need to diffuse two impurities and the cost is high.
