Diatoms, a type of phytoplankton, offer a promising solution due to their silica frustules, which can be processed into high-purity #silicon suitable for #SolarCell production. However, impurities in silicon can significantly reduce solar cell efficiency. A recent study employed Laser-Induced Breakdown Spectroscopy (#LIBS) to analyze the elemental composition of diatomite.
