DuPont Innovalight Announces Highest Efficiency Solar Modules Using Silicon Ink Technology

Key Customer Collaboration Combines Advanced Material and Process Technology to Set New Record

SUNNYVALE, Calif., May 16, 2012 –DuPont Innovalight announced today that Hyundai Heavy Industries (HHI) began mass production of solar cells using silicon ink technology from DuPont Innovalight. HHI has achieved over 19.5 percent median conversion efficiency with screen printed selective emitter solar cells made with DuPont™ Innovalight™ silicon ink on the HHI mass production line.


Hyundai Heavy Industries (HHI) has achieved over 19.5 percent efficiency in mass production with solar cells made using DuPont™ Innovalight™ silicon ink.

"HHI has manufactured the highest performance solar cells that we have seen in the industry so far using silicon ink technology," said Conrad Burke, general manager, DuPont Innovalight. "HHI is a very important customer for us, and we're pleased to recognize this accomplishment - it is the achievement of the combination of the HHI's mass production technology and the DuPont™ Innovalight™ silicon ink technology."

DuPont™ Innovalight™ silicon ink and processing technologies allow crystalline silicon solar cell manufacturers to boost output capacity, raise solar cell conversion efficiency as well as reduce costs with a simplified additional step to already installed manufacturing lines. Conversion efficiency refers to the percentage of electricity converted from sunlight in a solar cell.

LG Solar Unveils NeON R with Enhanced Aesthetics and Energy Savings

The NeON R module features "Back Contact" cell technology delivering an entirely black panel that is aesthetically pleasing and energy efficient. The cell's seamless, surface blends perfectly into nearly all rooftop designs while the module's electrodes are positioned on the rear of the cell. Using LG's N-type cell structure, the panels produce 365W of energy, up to 7.3kWp, compared to 5.8kWp of the p-type cell. The module's new design minimizes LID, thereby delivering a longer lifespan and increased energy output.
