DuPont And TSEC Show New High-Efficiency PERC Solar Cells


Taiwan-based TSEC Corp. has developed its new V-Series high-efficiency solar panels made with a new photovoltaic metallization paste from DuPont Photovoltaic Solutions.

The TSEC V-Series 300 W and 360 W solar panels use DuPont's Solamet metallization pastes that are formulated to help achieve improved conversion efficiency. The panels also employ DuPont Tedlar polyvinyl fluoride film-based backsheets.

TSEC signed an agreement with DuPont in late 2014 under which DuPont would create customized silver paste materials suited for lower-temperature processing in order to boost the efficiency of TSEC's passivated emitter and rear cell (PERC) solar cell architecture.

‘With Solamet pastes optimized for TSEC's V-Cell manufacturing process, we've hit our conversion efficiency target of over 21 percent – not just in the lab, but in production,’ says Tim Chang, Asia Pacific regional business director for DuPont's microcircuit materials group.
