Karlsruher Institut für Technologie (KIT) researchers have now produced perovskite/CIS tandem solar cells with an efficiency of nearly 25 percent – the highest value achieved thus far with this technology. In addition the new combination of materials is light and versatile, making it possible to envision the use of these tandem solar cells in vehicles, […]

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 […]

A Way Found to Use Perovskite to Make Fertilizer & Hydrogen
December 19, 2019 | Leave a Comment
Tokyo Institute of Technology scientists have found a way to synthesize a special type of perovskite that promotes the production of ammonia. Ammonia has key applications in fertilizer production and hydrogen energy. This new synthesis process can be carried out at temperatures immensely lower than that of traditional methods for the synthesis of perovskite-oxide materials […]

Perovskite Potential Grows For Use In LEDs
August 28, 2019 | Leave a Comment
Tokyo Institute of Technology scientists have discovered a new strategy to design incredibly efficient perovskite-based LEDs with record-setting brightness by leveraging the quantum confinement effect. Several techniques for generation of light from electricity have been developed over the years. Devices that can emit light when an electric current is applied, are referred to as electroluminescent […]

A Helmholtz-Zentrum Berlin für Materialien und Energie team has succeeded in producing inorganic perovskite thin films at moderate temperatures using co-evaporation – making post-tempering at high temperatures unnecessary. The process makes it much easier to produce thin-film solar cells from this material. In comparison to metal-organic hybrid perovskites, inorganic perovskites are more thermally stable. The […]
