About PERC Solar Cell

a. PERC (passivated emitter rear cell) is a new generation of solar cell technology which increases efficiencies via improving the transformation of solar energy into electric energy.

b. PERC Solar Cell Production Process 

c. PERC Solar Cell Advantage can further reduce the surface recombination rate (SRV[cm/s]) to increase the open-circuit voltage,the surface reflectivity and the short-circuited current(Isc).
