However, PERC technology brings new challenges with regard to the phenomenon of degradation: some monofacial\/bifacial PERC cell modules were found to demonstrate much higher power degradation than Al-BSF cell modules after damp-heat (DH: 85\u00b0C and 85% relative humidity RH, 1000h) and potential-induced degradation (PID: 85\u00b0C and 85% RH, \u20131,500V, 96h) tests, which will be the focus of this paper."}
