A New Solar Material Is Pushing Efficiency Beyond Theoretical Limits

For years, perovskites have been hailed as the "holy grail" of solar energy thanks to their promise of highly efficient and cheaper solar cells. Perovskites are a class of materials with similar crystalline structures with high superconductivity, high magnetoresistance, and high ferroelectricity, making them a potential replacement for silicon. Perovskite thin-film PV panels can absorb light from a wider variety of wave-lengths, allowing them to reach efficiencies of around 40% compared to silicon's theoretical limits around 30%. Unfortunately,…
