Trina Solar starts producing 210 mm n-type TOPCon solar cells
Trina Solar says its industrial tunnel-oxide passivated contact (i-TOPCon) solar cells, based on 210 mm wafers, have started rolling off the production line at its 8 GW factory in China. It will use the n-type cells to produce its new Vertex N modules, with power outputs ranging up to 605 W, and an efficiency rating of 22.4%.
Sunport claims to have reconciled back-contact and bifacial conundrum
The metal wrap-through-focused module maker revealed its M series at the SNEC solar conference in Shanghai, claiming a bifacial rate of up to 70%.
Trina claims another efficiency record, for n-type, i-TOPCon, bifacial cell
The 23.22% front-side efficiency of the 244.62 sq cm device – certified by Germany’s ISFH CalTeC – is another landmark for the Chinese manufacturer’s State Key Laboratory of Photovoltaic Science and Technology.
