Researchers at the University of California (UC) Riverside have discovered that the combination of two inorganic two-dimensional (2D) materials produces a quantum mechanical process that could significantly increase the efficiency of photodetectors, leading to revolutionary new ways of collecting solar energy.

In research described in the journal Nature Nanotechnology, the UC Riverside researchers have used the transition metal dichalcogenides  tungsten diselenide and molybdenum diselenide to achieve the effect known as electron-hole multiplication. Electron multiplication involves making multiple electron-hole pairs for each incoming photon. This can dramatically increase the efficiency of a photovoltaic cell in converting light into electricity.
