An international research group claims to have developed a new bulk perovskite semiconductor material that can capture the excess energy of hot electrons. The material is said to rapidly absorb as heat energy which would otherwise be wasted. With the harvesting of hot electrons, the maximum theoretical efficiency for hybrid-perovskite solar cells could increase from 33% to 66%.Hot electrons - also known as hot carriers - have high kinetic energy which, in a semiconductor, can have the undesired effect of remaining trapped in areas of the device where they shouldn't be. That can result in the ...Den vollständigen Artikel lesen ...
