Hot electrons harvested without tricks

hotelectrons 1


Semiconductors convert energy from photons (light) into an electron current. However, some photons carry too much energy for the material to absorb. These photons produce "hot electrons," and the excess energy of these electrons is converted into heat. Materials scientists have been looking for ways to harvest this excess energy. Scientists from the University of Groningen and Nanyang Technological University (Singapore) have now shown that this may be easier than expected by combining a perovskite with an acceptor material for hot electrons. Their proof of principle was published in Science Advances on 15 November.

In article number 1800116, Sergei A. Ponomarenko, Maxim S. Pshenichnikov, Dmitry Yu. Paraschuk, and co-workers propose an innovative concept of molecular self‐doping. The art shows how a highly luminescent dopant emerges as a minute‐amount by-product during the host material synthesis to enhance luminescence of organic crystals. The self-doping concept opens an easy route to highly luminescent semiconductor organic crystals for optoelectronics applications

Molecular Self-Doping Controls Luminescence of Pure Organic Single Crystals

March 14, 2018
Modern light-emitting devices such as top-level TV screens are based on organic luminescent semiconductor materials. The two key requirements for them are efficient luminescence and high charge carrier mobility. The latter requires tight molecular packing readily achieved in organic semiconductor single crystals, but it also results in inhibiting the light emission because of luminescence quenching. This dichotomy is resolved by doping of the host crystals with highly luminescent organic molecules which requires their chemical synthesis and subsequent smooth embedding into the host.
