Solar Cell Efficiency Gains Announced ( Solar Thermal Magazine )
Applied Materials, Inc. announced today that CECEP Solar Energy Technology Co., Ltd., a Chinese state-owned company focused on the research, production and installation of crystalline silicon solar cells and modules, achieved a key milestone of 18.32 percent average solar cell efficiency for its multi-cells. This increase was achieved on conventional production lines using a standard process upgraded with Fine Line Double Printing(TM) (FLDP(TM)) enabled by Applied’s Baccini(R) Esatto Technology(TM).
The milestone was reached in early December 2013, and the production line continues to maintain stable operation.
This result is crucial to meeting the “Photovoltaics Manufacturing Industry Standards” minimum cell efficiency requirement recently mandated by the government to qualify for capacity expansion, and to drive the development and advancement of China’s photovoltaic (PV) manufacturing and renewable energy industry.
“As new markets for solar PV emerge across China and competition increases, it is essential to accelerate the pace of innovation to achieve higher cell efficiencies,” stated Mr. Li Kai Jiang, CECEP General Manager.
CECEP is extremely proud to have reached its 18.32 percent efficiency target by upgrading to Applied’s Fine Line Double Printing with Esatto Technology. CECEP was able to conveniently and quickly implement double printing on existing systems to enhance the efficiency of our optimized standard multi cells. This result represents a 0.2 percent efficiency gain over our previous production baseline. Based on the high value of this collaboration, CECEP looks forward to working with Applied on further solutions to advance solar cell technology.
Applied’s FLDP Esatto Technology enables the precise double printing of advanced, high efficiency cell structures with a complete solution of production ready hardware, software, consumables and processes. Double printing enables production implementation of sub-50 micron lines to increase cell efficiency, improve yield and reduce paste consumption. Esatto technology incorporates an advanced pattern recognition system that adjusts printing and alignment parameters in real time to deliver the highest wafer to wafer repeatability. This level of advanced process control combined with paste optimization improves performance and yield while reducing cost. Esatto Technology comes with a proven best known method (BKM) to enable rapid implementation and ramp on Applied’s market-leading Baccini metallization and cell processing systems.
“China’s Ministry of Industry and Information Technology’s minimum requirement is further evidence of a 10 watt per year industry
efficiency clock” that is driving our customers to rapidly innovate to stay competitive,” said Jim Mullin, vice president and general manager of Solar Products for Applied Materials’ Energy and Environmental Solutions Group. “Applied is committed to enabling customers like CECEP to accelerate their roadmap with a portfolio of PV solutions that increase efficiency, improve yield, and reduce cost over multiple generations of cell designs.
