A team of semiconductor researchers based in France has used a boron nitride separation layer to grow indium gallium nitride (InGaN) solar cells that were then lifted off their original sapphire substrate and placed onto a glass substrate. The French team’s technique is the third major application for the hexagonal boron nitride lift-off technique, which […]

Challa V. Kumar, Ph.D working at the University of Connecticut reported today the development of a unique, “green” antenna that could potentially double the efficiencies of certain kinds of solar cells and make them more affordable. The report was presented at the 250th National Meeting & Exposition of the American Chemical Society held in Boston. […]

A University of New South Wales (UNSW) research team is converting over 40 percent of the sunlight hitting a solar system into electricity. The solar cell system has been independently confirmed by the National Renewable Energy Laboratory (NREL) at their outdoor test facility in the United States. 40 percent is a very big number, the […]

Scientists have reviewed chemists’ work on “singlet fission,” a process in which a single photon generates a pair of excited states. Singlet fission as a 1->2 conversion process has the potential to boost solar cell efficiency by as much as 30 percent. Chemists at the University of California, Riverside published a perspective article published last […]

The Fraunhofer Institute for Solar Energy Systems ISE, Soitec, CEA-Leti and the Helmholtz Center Berlin jointly announced achieving a new world record for solar cell efficiency.  Using a new solar cell structure with four solar subcells the team surpassed all the competition after only over three years of research.  The new record efficiency of 44.7% […]
