Reliance Industries has begun production at the first phase of its planned 10 GW solar module facility. The fully automated line manufactures heterojunction (HJT) panels with outputs of up to 720 W.

In January, INES and Italy-based heterojunction solar module manufacturer 3Sun, a unit of Enel, achieved a power conversion efficiency of 30.8% for a two-terminal tandem perovskite-silicon solar cell.
