Researchers find significant vendor variation in UV-induced degradation of TOPCon solar cells

A U.S. study of commercial tunnel-oxide passivated-contact solar cells reveals substantial performance differences across manufacturers in how cells degrade under ultraviolet light and recover in darkness, suggesting the need for standardiz
