Research and development

With robust and rigorous R&D, Trina Solar has been hard at work and our rapid rate of innovation has led to 852 approved patents.

Optimizing efficiency

Trina continues to advance efficiency boundaries, with both p-type monocrystalline and p-type multicrystalline cell conversion efficiencies reaching a respective 22.61(2016) percent and 21.25 (2015)percent respectively in the laboratory. Through technological innovation, we plan to continue breaking records and driving even higher efficiencies.

R&D partnerships

Trina’s State Key Laboratory for PV Science and Technology  ranks as one of the most advanced PV research center for the invention and innovation of applied technology in solar power. The 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.
