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.
