A New Class of Solar-Harvesting Material

LANL Perovskite

Perovskites are a new class of solar-harvesting materials able to form crystalline solar cells that are easy to work with, easy to adjust for improved performance, and very easy to afford. In recent experiments, Los Alamos National Laboratory (LANL) scientists have produced perovskite crystals that exhibit solar conversion efficiencies comparable to those of silicon, the current gold standard—and LANL achieved this level of efficiency in the first six months of research, compared with the decades it took to get silicon there.

These crystals are free of defects on exceptionally large scales and are therefore resistant to losing or trapping valuable photoelectrons. As LANL scientists continue to enhance their capabilities, perovskites show great potential for the commercial solar-energy market.
