Tongwei has partnered with GS-Solar and Golden Solar to establish a large-scale manufacturing facility for hybrid heterojunction back-contact (HBC) solar cells, focusing on technology development, manufacturing, and process optimization. The hybrid HBC technology aims to achieve high efficiency at lower production costs, streamlining processing. This collaboration could expedite the shift from laboratory-scale research to industrial production, broadening Tongwei's solar technology offerings. GS-Solar, positioning itself as a technology and equipment provider for hybrid HBC commercialization, has engaged in similar partnerships previously.
