Next Generation Industrial Bifacial Silicon Solar Cells

closed

The Next Generation Industrial Bifacial Silicon Solar Cells project brings together a consortium of ANU, GCL Technology Systems (China), and Wavelabs (Germany) to represent a complete spectrum in the PV industry encompassing R&D, manufacturing and device characterisation technologies.ANU as the project leader will be the hub of the collaboration between the groups, where fundamental studies, process innovation, technology demonstration and knowledge sharing activities are performed. Developed technologies at ANU will be transferred to industrial scale devices at GCL’s pilot factory, and new testing methodologies specifically related to bifacial cells will be developed and tested in collaboration with Wavelabs engineers.Key resultsThis project developed and applied multiple advanced fabrication technologies including laser doping, tunnel-oxide-polysilicon, and Oxide-Nitride-Oxide multi- functional film.The development of these technologies led to a successful demonstration of a record efficiency achieved using ‘laser doping’ technology on a 24.3% bifacial device with 96.3% bifacial factor.Industry collaboration led towards the development and advancement of polysilicon contact-based bifacial solar cells.
