Trina Solar Announces New Efficiency Records for Silicon Solar Cells
Trina Solar Announces New Efficiency Records for Silicon
CHANGZHOU, China, Nov.
17, 2014 -- Trina Solar Limited (NYSE: TSL) (Trina Solar or the Company), a
global leader in photovoltaic (PV) modules, solutions and services, today
announced that its State Key Laboratory of PV Science and Technology of China
has set new world records for high efficiency p-type and n-type
silicon solar cells.
The p-type mono-crystalline
silicon solar cell on an industrial Cz wafer, which integrates advanced
technologies including back surface passivation and local back surface field,
reached an efficiency of 21.40% (156 x156 mm2). This result has been
independently confirmed by Fraunhofer ISE CalLab in Germany. The same advanced cell
technologies on a high quality multi-crystalline Si wafer resulted in a new
champion p-type multi-crystalline silicon solar cell with an efficiency
of 20.53% (156 x156 mm2),
as independently confirmed by the National Center of Supervision and Inspection
on Solar Photovoltaic Product Quality (CPVT) in Wuxi, China. Both results
established new world records for mono and multi p-type silicon solar cells
with passivated rear surface and local contact, on 6 substrates and fabricated
with an industrial process. These cells are commonly called iPERC cells.
mono-crystalline silicon solar cell with an Interdigitated Back Contact (IBC)
structure and industrially feasible production process achieved an efficiency
of 22.9% on a 156 x156 mm2 n-type Cz wafer as independently tested
by Japan Electrical Safety & Environment Technology Laboratories (JET).
This marks another milestone in the development of IBC solar cells and comes
shortly after the demonstration of a laboratory IBC solar cell with a 24.4%
efficiency developed through Trina Solar collaboration with the AustralianNational
University (ANU) Centre for Sustainable Energy Systems in March this year.
To the Company
knowledge, these total-area efficiency results, independently verified by
external laboratories, affirm these cells to be in their categories the most
efficient silicon solar cells made by industrially feasible production
processes on 156mm x 156mm substrates for both p-type (mono
& multi) and n-type (mono) substrates that have been tested anywhere
in the world to date.
We are very pleased
to announce these new efficiency results achieved by Trina Solar researchers at
the State Key Laboratory of PV Science and Technology, said Dr. Pierre Verlinden,
Vice President and Chief Scientist of Trina Solar. Though these technologies
are not currently in production, they will be part of our future commercialized
Honey Plus and IBC products. Our aim is to continuously integrate technological
developments into our PV products, which are currently commercialized or would
be in the future, to further drive down the product cost, strengthen our
competitive advantages and provide affordable solar power to the world. We
believe that innovation is core to Trina sustainable growth and long-term
success. Our focus remains on developing innovative and cutting-edge solar
power products and technologies to strengthen our leading position as a premium
