Trina Solar launches N-type i-TOPCon double-glass bifacial modules
CHANGZHOU, China, June 13, 2019/PRNewswire-AsiaNet/--

Trina Solar, the 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 world record efficiency of 25.8% on small-area, single side TOPCon cells 
developed by Fraunhofer ISE has driven research and development of passivated 
contact solar cells by institutes and industry. In 2015, the State Key 
Laboratory of Photovoltaic Science and Technology (SKL PVST) of Trina Solar 
started the research on a large-area bifacial TOPCon cell that is aimed for 
industrial mass production, naming it i-TOPCon cell. In 2019, Trina Solar 
achieved a front side median efficiency over 23% on i-TOPCon cells.

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.
