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…

New solar materials opportunities: glass frontsheets, anti-reflective coatings

By / June 3, 2011

Credit: SolarWorld. A lot of attention is paid to making photovoltaic modules more cost-effective by reducing the costs associated with the active materials, and, indeed silicon prices seem to be dropping (with estimates of somewhere between 5 and 7 percent for the first quarter of 2011, after similar drops in 4Q 2010) despite double-digit growth…

24% PV efficiency

By / June 25, 2010

Good for SunPower. This 24% efficiency was reached in a large silicon PV wafer, not just a test unit a lab.
