A positive negative outlook

While p-type (positively-doped) passivated-emitter rear contact (PERC) solar cells are unlikely to disappear any time soon, n-type technology is gaining ground, with tunnel-oxide passivated-contact (TOPCon) expected to lead the charge into the new normal. S&P Global Commodity Insights’ Karl Melkonyan takes a look at the n-type runners and riders.

High-efficiency n-type modules still fetch a premium over p-type PERC products. But as panels with positively-doped wafers reach their conversion efficiency limits, solar manufacturers are going negative, usually via TOPCon or heterojunction (HJT) technology.This investment shift has been enabled by optimization including raised efficiency, cost reduction, extended product lifetimes, and rising standardization. Against that background, …
