Trina Solar, a world leading global PV and smart energy total solution provider, recently announced that it has begun mass production of N-type i-TOPCon double-glass bifacial modules. The best front side power output of a module with 144 half-cut i-TOPCon cells reaches 425 Wp, and the best module efficiency reaches 20.7%.
The new i-TOPCon double glass PV modules integrate these N-type bifacial i-TOPCon cells with over 80% bifaciality, multi-busbar (MBB) design, full square monocrystalline cells, dual-side and half-cut technologies. The highly efficient modules feature a lower temperature coefficient and low light induced degradation (LID), greatly improving the actual power output. They also provide an extra 5% to 30% power generation from their back side, and feature a 30-year linear power warranty.
The i-TOPCon cell has a front boron emitter and a rear full-area passivating contact. After its development by the SKL PVST, it was transferred into full-scale mass production in a workshop at Trina Solar’s Changzhou factory. In May 2019, Trina Solar announced that its SKL PVST has set a new world record of 24.58% for such n-type mono-crystalline silicon (c-Si) i-TOPCon solar cells. This result was independently confirmed by the ISFH CalTeC in Germany with a full-area measurement (244 cm2) including busbars.
