Power potential well above announced public roadmaps 2. Improved energy yield due to T coefficient and bifaciality 3. Adapted to thin wafer leading to cost reduction and LCA benefit Looking for Industrialization of HJT technology at GW scale associated to a development Roadmap towards Tandem for 30. Collecting additional data regarding SHJ production yield benefits at the MW level including new features like tracking, cleaning SHJ A 10 GW EcoSystem is rising up For the next three years Solar for Solar.
