Scientists have discovered that graphene is able to convert 90% of sunlight into electricity

The International Research Group has discovered that combining graphene elements of various geometric forms can be achieved by converting 90% of sunlight into electricity.

Grafen is a material that is made of one layer of carbon atoms combined into a hexagonal grille. In addition to good strength indicators, it has high heat and electrical conductivity, and is also capable of absorbing the light of any frequency, which makes it an ideal material for photodetectors of wide use, biosensors and photocells.

Combining graphene ribbons, crosses and cylinders between wide rectangular flat sheets, scientists have established that when sunlight enters the plots of their compounds, a strong photo program is formed in the material. Researchers argue that with proper structuring, the material is potentially capable of transforming light into electricity with an efficiency of 90%.

In most solar batteries, the photoconducy occurs only in the presence of a compound of two heterogeneous materials, such as P-N transitions, boundaries between the two types of semiconductors. However, in pure graphene, the photoelectron emission occurs when the sheet is completely deprived of excess electronic charge and absolutely neutral. The generation of the photocurrent does not require special transitions, instead, the process can be controlled by means of a simple cutting and molding of the graphene sheet into unusual configurations.

Researchers say that the material can be used to create translucent devices suitable for location on windows, cars or combination with traditional photocells for collecting energy, which is usually not absorbed. At the moment, scientists are concentrated on the study of the mechanism for the interaction of material with the radiation of the infrared spectrum.
