Title:
PHOTOCONVERSION DEVICE BASED ON GRAPHENE WITH ENHANCED PHOTON ABSORPTION
Document Type and Number:
WIPO Patent Application WO/2013/110803
Kind Code:
A3
Abstract:
An infrared photoconversion device comprising a collector with at least an active layer made of a single sheet of doped single-layer, bilayer, or multilayer graphene patterned as nanodisks or nanoribbons. The single sheet of doped graphene presents high absorbance and thus, the efficiency of devices such as photovoltaic cells, photodetectors, and light emission devices can be improved by using graphene as the central absorbing or emitting element. These devices become tunable because their peak absorption or emission wavelength is changed via electrostatic doping of the graphene.
