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. When illuminated, electrons collect on one side of the walls and holes on the other, driving the current at right angles to the walls. Voltage…

Solid-state photovoltaics offer new path to solar energy

By / March 30, 2010

According to a Lawrence Berkeley National Laboratory press release, researchers have discovered a new path to convert sunlight to electricity. Researchers have found a new mechanism by which the photovoltaic effect can take place in semiconductor thin films. This new route to energy production overcomes the bandgap voltage limitation that continues to be detrimental to…
