Solar & Alternative Energy

High-efficiency solar panel

DuPont Photovoltaic Solutions and TSEC Engineering

DuPont Photovoltaic Solutions (DuPont) and TSEC Corporation (TSEC) introduce TSEC's newest "V-Series" high-efficiency solar panels.

The solar cells in the V-Series panels are made using new DuPontTM Solamet® photovoltaic metallization pastes that have been customized and optimized to help achieve more efficient conversion of sunlight to electrical energy, thereby significantly improving the panel's power output.

The panels also are protected by DuPontTM Tedlar® polyvinyl fluoride film-based backsheets that are proven to deliver long-term reliability for 25 years or longer, under all-weather conditions.

TSEC signed an agreement with DuPont in late 2014 establishing a collaboration under which DuPont would create customized silver paste materials suited for lower temperature processing in order to boost the efficiency of TSEC's proprietary Passivated Emitter and Rear Cell (PERC) solar cell architecture. Use of the new Solamet® silver pastes on the front and rear side of the solar cells allowed TSEC to gain an additional 0.15 percent conversion efficiency to push the total to over 21 percent, its highest yet for this type of solar cell. Increasing efficiency helped improve the power output of the V-Series panels to more than 300 watts and 360 watts in 60-cell and 72-cell configurations, respectively. Higher efficiency also lowers overall system costs and improves the return on investment for solar energy systems.
