DuPont Photovoltaic Solutions introduced new innovations for its DuPont Solamet photovoltaic metallization paste to enable advanced screen printing at the 2017 International Photovoltaic Power Generation Expo in Tokyo, Japan.
Specially designed for double printing, Solamet PVD1x and PVD2x comprise an integrated two-layer solution with excellent compatibility to maximize cell performance.
The first layer demonstrates super low contact resistance and excellent fine line printing, while the second layer delivers better electrical conductance and good solderability for high adhesion. This leading solution for double printing enables more than 0.1 percent efficiency gain.
DuPont also introduced Solamet PVM1x to support the new development of the Mesh-Cross-Free (MCF) screen. Solamet PVM1x has excellent matchability with various MCF parameters, outstanding printability and yield to both multi and mono wafers with 0.1 percent efficiency gain.
At the Expo, DuPont is collaborating with Taiwan Solar Energy Company (TSEC) to demonstrate the increased efficiency and power output that DuPont Solamet technology can provide.
TSEC, which specializes in manufacturing high performance, top quality mono- and polycrystalline silicon solar cells and modules, has observed 21.15 percent cell efficiency and module power output as high as 305 Watts (60 pcs) in its mono PERC modules.
