JinkoSolar and Trina Solar both report in white papers that on-field testing demonstrates that tunnel oxide passivated contact (TOPCon) modules outperform p-type back-contact PV modules in power generation each month. Apparently, the TOPCon product showed an average energy yield of 2.22%, up to 6.95% higher than its p-type back-contact counterpart.
