Trina Solar Ltd. and the Australian National University (ANU) have jointly developed a new high-efficiency solar cell.
The interdigitated back contact (IBC) cell was developed at the ANU's Center for Sustainable Energy Systems under a research and development contract with Trina Solar through a collaboration contract with the Solar Energy Research Institute of Singapore. The IBC silicon solar cell was independently tested by the Fraunhofer CalLab in Germany to be able to deliver an efficiency of 24.4%.
Trina Solar is developing a commercial version of the IBC solar cell, as well as an IBC PV module. Trina says the commercial cell has already reached an efficiency greater than 22% as certified by China's national PV products quality testing center.
