Bismuth ferrite research sheds light on increasing PV efficiency

By Eileen De Guire / September 19, 2011

At top, domains with opposite electrical polarization, averaging about 140 nanometers wide and separated by walls 2 nanometers thick, form a well-aligned array in a thin film of bismuth ferrite.…
