Optical materials news, November 2019

Scientists have found an organic compound that can harvest the 'hot electrons' produced when high-energy photons hit a perovskite semiconductor.

Researchers have developed new organic-inorganic hybrid perovskite materials that don't contain lead and have a much improved stability.

Perovskite materials for use in next generation solar cells and flexible LEDs can be more efficient when their chemical compositions are less ordered.

By applying an intermittent electrical field, researchers have managed to get blue-phase liquid crystals to adopt novel structures with novel properties.

By replacing some of the lead in perovskites with indium, scientists have quashed the defects in perovskite solar cells and enhanced their stability.

Exposing the cathode in a lithium-ion battery to a beam of concentrated light can lower the charging time by a remarkable factor of two or more.

By wetting porous polymer coatings with alcohol, researchers have come up with an inexpensive and scalable way to control light and heat in buildings.
