Industry Partners to Commercialise Hydrogenation Technology


Industry partners from around the world are initiating advanced hydrogenation processes developed at UNSW.

  • UNSW advanced hydrogenation technology completely solves Light Induced Degradation in P-type cells caused by Boron-Oxygen defects
  • A consortium of the largest manufacturers in the world is collaborating with UNSW on the advanced hydrogenation technology
  • Industry partners are now starting to incorporate the advanced hydrogenation technology in their production facilities

“Our advanced hydrogenation technology offers real commercial benefits to our industry partners,” says A/Professor CheeMun Chong.  “By using advanced hydrogenation, we can significantly improve cell efficiency as well as completely remove Light Induced Degradation for cells fabricated on p-type CZ silicon wafers.”

Over time, the performance of silicon PV modules drops by as much as 25% (at end of life).  Using the advanced hydrogenation technology, industry partners now have the opportunity to stop this degradation.  For the first time, manufacturers have the opportunity to fabricate PV modules that can generate the same output power at end of life as on their first day of use.  “This is a significant advantage, not only for the manufacturers but also for the end users,” says Scientia Professor Stuart Wenham.

Industry partners already include many of the world’s largest manufacturers.  While it is unusual for these competitors to collaborate, this technology offers such tangible commercial benefits that they choose to work together.

“Industry is close to commercialising these processes,” continued Scientia Professor Stuart Wenham.  “Even at this late stage, it is still possible for a limited number of additional companies to participate.”

Research in this area was funded through ARENA as well as by industry.
