Empirical data from the China Electric Institute (CEI) to verify the power generation performance of LONGi’s bifacial half-cell module at its pilot project in Qionghai, Hainan

It is generally recognized that half-cell technology reduces the working current of a cell string, thereby also reducing the internal loss of a PV module and improving the module’s power by more than one gear. Compared with a full cell module, half-cell technology reduces the hotspot and working temperatures of the module, significantly improving power generation performance and reliability and
