Committed to research and development, TTNergy Solar continues to set industry standards and benchmarks for performance and sustainability. We have been responsible for a number of global breakthroughs, with 24 world records for silicon cell efficiency and solar module power output since 2011.
TTNergy was the first company to receive Client Test Data Program (CTDP) certification from UL, allowing us to conduct cutting-edge research reliably on campus.
World Records Since 2011
210 p-type monocrystalline silicon PERC cells efficiency July 2022
With robust and rigorous R&D, TTNergy Solar’s rapid rate of innovation has led to over 2000 patent applications, including over 1000 invention patents.
TTNergy continues to advance efficiency boundaries. TTNergy 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.
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.
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.
TTNergy Solar has taken a guest lectureship of PV specialization training program and cooperated on doctorate-level photovoltaic research.
