Mg-doped C60 thin film as improved n-type organic semiconductor for a solar cell

Mg doping effect on a [2-methoxy, 5-(2′-ethylhexyloxy)-1,4-phenylene-vinylene] (MEH-PPV)/C60 bilayer solar cell has been investigated. We find that the Mg doping occurs during the deposition of the Mg top electrode onto the C60 film and that the solar cell property is markedly improved by the doping...

Description
Summary:Mg doping effect on a [2-methoxy, 5-(2′-ethylhexyloxy)-1,4-phenylene-vinylene] (MEH-PPV)/C60 bilayer solar cell has been investigated. We find that the Mg doping occurs during the deposition of the Mg top electrode onto the C60 film and that the solar cell property is markedly improved by the doping. The power conversion efficiency of the Mg-doped device under 100 mW/cm2 white light illumination is 0.54%, which is approximately 400 times larger than that of the nondoped device.
