CHANGZHOU, China, Feb. 28,2014 /PRNewswire/ -- Trina Solar Limited ("TSL" or
"Trina Solar"), a global leader in photovoltaic modules, solutions and
services, announced today that researchers from Trina Solar and the Australian
National University ("ANU") have jointly developed a new high-efficiency solar

The laboratory scale Interdigitated Back Contact ("IBC") cell was developed at
the Australian National University Centre 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 (SERIS). After
two years of research, funded by Trina Solar, the ANU has developed, with
contribution from Australian consulting firm PV Lighthouse, an IBC silicon
solar cell, which was independently tested by the Fraunhofer CalLab in Germany
to be able to deliver an efficiency of 24.4%, putting it among the most
efficient solar cells to date.

Trina Solar is now developing a commercial version of the IBC solar cell as
well as an IBC PV module. The commercial cell has already reached an
efficiency greater than 22% for a 125mm by 125mm IBC solar cell, and 238W for
an IBC PV module (based on 72 cells), which was independently tested by the
National Center of Supervision and Inspection on Solar Photovoltaic Products
Quality of China. Though it is currently in laboratory scale, the new solar
cell will soon be ready for industrialized mass production.

"We are delighted to collaborate with leading scientists at ANU on this
exciting new development in our cell technologies," said Dr. Pierre Verlinden,
Vice-President and Chief Scientist of Trina Solar. "This marks a milestone in
solar cell research with an improved IBC cell efficiency of 24.4%. This
world-class efficiency demonstrates our commitment to leading innovation in PV
technology. We remain committed to engaging in effective partnerships with the
best PV research centers, which are fundamental to delivering R&D

"This is the highest efficiency independently confirmed for a conventional IBC
solar cell to date," said Professor Andrew Blakers, Director of the Centre for
Sustainable Energy Systems at the ANU Research School of Engineering. "The
results mean the laboratory cell technology can now be further developed for
commercial solar cells. The work is expected to lead to commercial solar cells
with improved efficiency, allowing more power to be generated from a given
area of rooftop solar module."

Professor Blakers added, "The ANU has been working to develop highly efficient
back contact silicon solar cells, which have both positive and negative
metallic contacts on the rear surface. That allows the surface facing the sun
to be uniformly black, without the metal electrodes present on most solar
cells. The back contact cell structure enables the end user to gain more
electricity per unit area and a more favourable appearance."
