Trina Solar, a global leader in solar energy innovation, has unveiled its new n-type i-TOPCon Advanced technology to the world.

The technology was given its first public viewing on the first day of the International Solar Photovoltaic Power Generation and Smart Energy Conference and Exhibition in Shanghai. From next year the Vertex n-type series will be upgraded, with the most powerful module in the series generating more than 700W, the company announced.

At the exhibition Trina Solar also announced that work on Phase II of its 15GW monocrystalline silicon ingot project at its factory in Xining, Qinghai province, has begun. Work has also begun on its 10GW n-type high-efficiency cell and 10GW n-type module project in Yangzhou, Jiangsu province.

In addition, Trina Solar has taken the lead in establishing a net-zero system by initiating the Environmental Product Declaration and carbon footprint certification for its Vertex Nmodules.

Trina Solar consistently leads the industry in n-type technological innovation. At the launch, Dr Chen Yifeng, associate vice president of Trina Solar, underlined the importance of four innovations: the 210R rectangular cell, the selective boron emitter, the backside microstructure reflector, and the highly doped TOPCon structure with PECVD.

These have enabled new-generation i-TOPCon Advanced technology to deliver potential production efficiency of 26%, with module power output of up to 700W.

Typically for utility power plants, the Vertex N modules with power up to 700W further reduce LCOE and will come to mass production next year.
