摘要:
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.

摘要:
Embodiments of the present invention generally include methods for forming semiconductor films having nominal I2-II-IV-VI4 stoichiometry, such as CZTS or CZTSSe, using a solution of including sources of the I, II, IV, and VI elements in a liquid solvent. Precursors may be mixed in the solvent to form the solution. Metal halide salts may be used as precursors in some examples. The solution may be coated onto a substrate and annealed to yield the semiconductor film. In some examples, the source of the 'I' and 'IV' elements may contain the elements in a +2 oxidation state, while the semiconductor film may contain the 'I' element in a +1 oxidation state and the 'IV' element in a +4 oxidation state. Examples may be used to provide I2-(II,IV)-IV-VI4 films.
