Dow Corning and Reis Robotics have announced that their solar cell liquid encapsulation process has passed factory acceptance testing and is now available for commercial use. Additional site testing was conducted on the pilot line at the new Dow Corning Solar Solutions Application Center in JinCheon, Korea with a world-leading manufacturer of high-performance solar power products.
Module durability and efficiency has often been at odds against the need to reduce capital and manufacturing costs, while significantly increasing the production rate of solar module assembly steps.
The new technology enables solar module manufacturers to use Dow Corning PV-6100 Cell Encapsulant Series and Reis equipment to achieve higher production rates for crystalline and amorphous silicon thin film modules, reducing the cost per kilowatt-hour of solar power. The liquid encapsulation process provides a clear laminate to protect each solar cell in a panel and can replace commonly used ethyl vinyl acetate resin. Panel manufacturers can increase efficiency and reduce total cost of ownership through lower processing temperatures, and faster throughput. The system chemistry and process were fine tuned to reduce cycle times while maintaining low temperatures. The process is claimed to require lower capital and less factory space, due to the throughput increase.
Solar cell liquid encapsulation.
Dow Corning PV-6100 Encapsulant Series relies on the UV stability of the silicone molecule to deliver improved durability and increased efficiency for crystalline modules compared to incumbent organics. The liquid silicone-based material provides an ultra-transparent layer of protection for the solar cell in a panel and outperforms incumbent organics in durability, efficiency, module life and UV resistance, providing greater protection for solar cell modules.
