A Penn State research team suggests that using two thin films of different materials may be the way to go to create affordable, thin film cells with about 34% efficiency. Solar cells have come a long way, but inexpensive, thin film solar cells are still far behind the more expensive, crystalline solar cells in efficiency. […]

Oak Ridge National Laboratory and the University of Tennessee, Knoxville have discovered a way to slow phonons, the waves that transport heat. The discovery could improve novel hot-carrier solar cells, which convert sunlight to electricity more efficiently than conventional solar cells by harnessing photogenerated charge carriers before they lose energy to heat. ORNL’s Michael Manley […]

Research by scientists at the Eindhoven University of Technology and universities in China and the US are exploring the causes of perovskite degradation in sunlight. The research may pave the way for designing new perovskite compositions for the ultimate stable solar cells. Perovskite solar cells are at the center of much recent solar research. The […]

Iowa State University engineers have developed a next-generation perovskite solar cell that takes advantage of the promising electro-optical properties of perovskite materials. They’ve made the materials much more stable at high temperatures and demonstrated a consistent, clean way to fabricate them into solar cells. These would be important steps toward commercial production of new, low-cost, […]

Los Alamos National Laboratory researchers have developed new quantum dot solar cells that match the efficiency of existing quantum-dot based devices, but without lead or other toxic elements relied on by most solar cells of this type. Victor Klimov, a physicist specializing in semiconductor nanocrystals at Los Alamos and lead author of the report featured […]
