DuPont and Applied Materials have teamed to boost the performance of c-Si solar cells. Applied is focusing on reduce the shadowing effect of wide grid lines on solar cells employing its Baccini ‘Esatto’ technology and customized formulations of DuPont’s ‘Solamet’ metallization paste.
“This collaborative technology will optimize the efficiency of solar cells and meet the needs of the market by ultimately lowering total system cost,” said Marc Doyle, global business director – DuPont Photovoltaic Solutions.

“We’re working with innovative suppliers like DuPont to integrate highly customized material formulations with our leading-edge solar manufacturing systems to drive down the cost per watt of solar energy,” commented Charles Gay, President of Applied Solar at Applied Materials. “By using our Baccini back end systems equipped with Esatto Technology and DuPont Solamet photovoltaic metallization paste, customers can achieve the precision alignment, repeatability and process control that enables successful multiple printing.”
The aim is to develop narrower and taller grid lines that will precisely print in two or more layers, which allow more cell surface area, boosting cell efficiencies.
