DuPont Microcircuit Materials (MCM) has introduced DuPont Solamet PV416 photovoltaic metallization paste, a new front-side silver paste material that is designed to raise the efficiency of thin-film photovoltaic cells.
This new silver composition has the capability to be processed at temperatures lower than 140 degrees C and provides improved contact resistance, conductivity, adhesion and fine line resolution when printed on transparent conductive oxides (TCOs), according to DuPont MCM. These properties are for improved performance in copper indium gallium (di)selenide (CIGS), amorphous silicon, and organic PV cells and modules.
The material has most recently been adopted at Midsummer AB, where it has demonstrated a 0.5% increase in conversion efficiency on stainless-steel-based CIGS cells, DuPont MCM adds.
