Sunrise Global Solar Energy Achieves 20.3 Percent Efficiency with New DuPont™ Solamet® Photovoltaic Metallization Pastes
Advanced Aluminum Pastes Significantly Boost Electrical Performance of Solar Cells
TAOYUAN, TAIWAN, Feb. 25, 2013 – DuPont Microcircuit Materials (MCM) and Sunrise Global Solar Energy Corporation announced today that they have produced solar cells with conversion efficiencies of 20.3 percent using newly commercialized DuPont™ Solamet® PV36X series aluminum photovoltaic metallization pastes for rear-side passivation of silicon solar cells. Sunrise Global Solar Energy, a world leading solar cell producer in Taiwan, reported that results with its latest CELCO high-efficiency solar cell design were independently verified by certified global standards group, Fraunhofer ISE in Germany. High performance solar panels with electrical output power greater than 280 Watts were produced and certified by independent certification group, TÜV Rheinland. Higher conversion efficiencies allow for greater electrical power generation in solar cells.
DuPont™ Solamet® photovoltaic metallization materials have allowed the conversion efficiencies of mass produced solar cells to nearly double over the past 12 years. Through continued investment in research, development and intellectual property, DuPont continues to focus on increasing solar cell efficiency, extending module lifetime and lowering overall system costs to make solar energy more competitive with other sources of electricity.
“Our collaboration with Sunrise Global Solar Energy has yielded excellent results,” said Peter Brenner, photovoltaics global marketing manager - DuPont Microcircuit Materials. “This successful commercialization of high performance solar cells, when coupled with the right materials, continues to lower the cost of producing electricity with solar energy.”
DuPont™ Solamet® PV36X series pastes can achieve greater cell efficiency gains compared with traditional aluminum pastes due to better electrical contacts and stronger adhesion. The new cells also exhibit strong resistance to a phenomenon known as potential induced degradation (PID) which has been observed in competing solar cell designs, where performance can decrease. DuPont has also reduced total paste usage on each cell and continues to focus on further improving the reliability and durability of solar modules.
DuPont has been supplying materials into the solar industry for over 30 years. Over 150 million solar panels installed worldwide contain DuPont materials.
DuPont Microcircuit Materials has over 40 years of experience in the development, manufacture, sale and support of specialized thick film compositions for a wide variety of electronic applications in the photovoltaic, display, automotive, biomedical, industrial, military and telecommunications markets.
