N-Type 450W 440W All Black TOPCon Solar PV Panel

All standard silicon solar panels are composed of silicon wafers mixed with various chemicals, generating power production. The difference between P-Types and N-Types involves the chemicals used during manufacturing. Specifically, boron is the chemical mixed with the silicon wafers in a standard P-Type solar panel. Boron has one less electron than silicon, which makes the solar cell positively charged. On the other hand, an N-Type solar cell uses phosphorus, which has one more electron than silicon, and this makes an N-Type solar cell negatively charged.

The long haul through trial and error in the solar industry has reached a place where it is clear that N-Type solar cells are the more efficient path forward. WEUP already developed a top-of-the-line N-Type solar cell, but it has also proven that this is the path forward by setting a new world record for efficiency.
