N-Type TOPCon technology (mono)

N-type technology uses phosphorus-doped monocrystalline cells (size 182 x 91 mm), where electrons are the majority carriers, which provides higher module efficiency (up to 22.5%) and better performance at high temperatures than P-type cells. In P-type, boron-doped silicon is more susceptible to LID light degradation and boron-oxygen complex recombination, while N-type in these lightweight modules (5.5 kg/m²) is less sensitive, allowing power to be maintained closer to initial value and justifying low annual warranty depreciations (0.4–0.55%/year, ≥84.8–89.4% after 25 years). The higher carrier lifetime in N-type gives the potential for cell efficiency >26%, and in these models, this is supported by high-transmission tempered glass, which reduces optical losses and lowers LCOE in lightweight rooftop modules.
