Transparent Electrode Increases Solar Cell Efficiency

July 14, 2021 | Leave a Comment

Open Image…Save ImageOpen Image (using #TmpD/ia)… Penn State researchers have developed new ultrathin metal electrodes allowing the creation of semitransparent perovskite solar cells that are highly efficient and can be coupled with traditional silicon cells to greatly boost the performance of both devices. The research represents a step toward developing completely transparent solar cells. Kai Wang, assistant research professor of […]

New Process May Create Higher Efficiency Solar Cells

September 6, 2018 | Leave a Comment

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 […]

Double Solar Cell Efficiency With An Antenna

August 19, 2015 | Leave a Comment

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. […]

Aussies Hit 40% Solar Cell Efficiency

December 17, 2014 | 1 Comment

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 […]

Singlet Fission in Solar Cells Gains Credence

July 10, 2014 | Leave a Comment

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 […]
