Sandia-led center to advance understanding of new solar panel technology
The Department of Energy recently awarded $14 million to form a Sandia National Laboratories-led center to improve the understanding of perovskite-based photovoltaic technologies and determine the best tests to evaluate the new solar panels’ lifetimes.
Defects Slow the Electron’s Dance
Researchers used two advanced microscopy techniques to learn how crystal defects affect the performance of crystalline solar cells called lead halide perovskite cells. The research used two microscopy techniques: electron backscattering diffraction to view crystal quality at scales of 100 nanometers and ultrafast microscopy to examine how electrons move. The research shows that microscopic defects that form when the crystals are made can reduce how fast electrons move by a factor of almost 10.
Finding the beat: New discovery settles a long-standing debate about photovoltaic materials
Scientists have theorized that organometallic halide perovskites— a class of light harvesting “wonder” materials for applications in solar cells and quantum electronics— are so promising due to an unseen yet highly controversial mechanism called the Rashba effect. Scientists at the U.S. Department of Energy’s Ames Laboratory have now experimentally proven the existence of the effect.
