Optimizing efficiency

Trina continues to advance efficiency boundaries. Trina Solar State Key Laboratory of PV Science and Technology of China has set a new world record of 23.22% with n-type i-TOPCon Solar Cell on Cast-mono substrate in Nov. 2019. In June 2021, Vertex high-efficiency p-type monocrystalline silicon module, based on 66 pcs of 210 mm x 210 mm high-efficiency PERC cells, has achieved a record aperture module efficiency of 23.03% for larger-area industrial silicon p-type modules. Through technological innovation, we plan to continue breaking records and driving even higher efficiencies.

Partnerships for progress.

As one of the most advanced PV research centers for solar technology, Trina's lab has welcomed research collaboration and partnerships with other leading technology and science centers to create cutting-edge solar solutions and products.

Solar Energy Research Institute of Singapore

Together, we collaborated on the development of a back contact solar cell. We are targeting 21.5 percent production cell efficiency, and up to 23.5 percent laboratory test cell efficiency within 3 years.

Australian National University

Working with ANU, we have achieved 24.4 percent maximum conversion efficiency in the laboratory for n-type mono c-Si IBC cells. Small-scale pilot production can currently reach a maximum conversion efficiency of 21 percent, and engineers are currently manufacturing the corresponding mass production line.

Universidad Politécnica de Valencia

Trina Solar has taken a guest lectureship of PV specialization training program and cooperated on doctorate-level photovoltaic research.
