Integrated Industrial Chain

GCL has built the silicon energy industry chain globally, and further deployed the intelligent manufacturing bases for granular silicon, wafers, cells and modules to promote PV as an indispensable eco-value co-constructor in the carbon neutrality system.

FBR Granular Silicon

GCL Tech's commitment to research over the past decade has paid off with the successful development of GCL-FBR granular silicon, and entered the era of “systemization, standardization, digitization, integration, intelligence and modularization”, making replication possible.
