Laser-induced breakdown spectroscopy (LIBS) has been employed for the fast and reliable chemical characterization of silicon used for the photovoltaic industry. Silicon for photovoltaic panels is subject to certain constraints on its purity, and notably must contain low concentration of boron. The use of LIBS could be advantageous because it allows rapid and simultaneous multi-elemental chemical analysis of silicon without any sample preparation. LIBS was applied to boron analysis and a detection limit of 0.23 ppmw was found for optimized gas and pressure conditions.

Climate Literacy

<div> </div><div>To move forward with substantial, constructive actions that reduce overall consumption and emissions, the public, scientists and policymakers need agreement about our terms. Terms like "sustainability," "zero-emissions" and "carbon-neutrality" tend to focus on a device or vehicle's energy use and emissions during operation--and to exclude energy use and emission during extraction, smelting, manufacturing and recycling or discard. What do such exclusions mean for e-vehicles, smartphones and solar panels? How can we encourage learning about and reducing electronics' true costs? Katie Singer will describe the process involved in manufacturing electronic-grade silicon (similar to solar-grade silicon), and propose that every Internet user learn the international supply chain of one substance (of 1000+) in their device. She will also propose ways to counterbalance a digital footprint. </div>
