【Product description】
N-type Mono bifacial PERT (passivated emitter rear totally diffused) silicon solar cells possesses high and stabilized conversion efficiencies.
The n type bifacial PERT solar cell can be manufactured with process flow by using ion implant for single-sided doping for excellent emitter junction quality and uniformity, a single thermal anneal, integrated AlOx/ SiNx passivation layer and screen printed Ag grid on front and rear.
【Process flow】
【Key features】
High conversion efficiency with high reliability
No light-induced degradation
Uniform cell performance with stable process control
Both sides can generate electricity
Excellent power generation performance under low irradiation
Low hot spot risk
