Mongabay: Solar cells, flat-panel screens are source of greenhouse gas 17,000 times more potent than CO2 Atmospheric concentrations of nitrogen trifluoride — a gas used in the manufacture of liquid crystal flat-panel displays, thin-film photovoltaic cells and microcircuits — are at least four times higher than previously estimated, reports a new study published in the journal Geophysical Research Letters. Using a technique that measures the prevalence of nitrogen trifluoride for the …
