DuPont Microcircuit Materials (MCM) (Bristol, UK) has introduced DuPont™
Solamet® PV416 photovoltaic metallization, a new frontside silver paste
material used to raise the efficiency of thin film photovoltaic cells. This
new silver composition has the capability to be processed at temperatures
less than 140°C, and provides improved contact resistance, conductivity,
adhesion and fine line resolution when printed on Transparent Conductive
Oxides (TCOs), all key properties for improved performance in Copper Indium
Gallium (di)Selenide (CIGS), amorphous silicon (a-Si), and Organic
Photovoltaic (OPV) cells and modules. The material has most recently been
adopted at Midsummer AB, where it has demonstrated a 0.5 percent increase in
conversion efficiency on stainless steel-based CIGS cells.
