A new generation of optoelectronic materials for various applications

Recently, scientists from National Center for Photovoltaic Research and Education conducted research on optoelectronic materials. The results have led to the improvement of existing semiconductor nanocomposites.


A new generation of optoelectronic materials

The team focused on optoelectronic elements capable of transform light into electrical energy. These miniature components are located in semiconductors mainly used in the photovoltaic industry and in the manufacture of OLED screens.

Apollo Optical Systems, world leader in the manufacture of polymer optical components, contributed to the success of this research. The results were published in the journal ScienceDirect.

They used cluster tool which moves optoelectronic semiconductors

Ordinary silicon photovoltaic cells do produce electrical energy, but recent findings suggest a possibility of improving these composites. To achieve this, the researchers first opted for perovskite solar nanocomposites. However, it turned out that a tandem installation with silicone elements provides better performance.

On the other hand, this technological revolution profoundly modifies assembly processes new devices that use light control. The new composites are indeed very sensitive to the external environment. Therefore, their handling requires special precautions.

Therefore, the engineers adopted a cluster tool that moves in-process optoelectronic semiconductors through connected rooms. This process eliminates the risk of infection of the microcomposites located in the devices.

The first pallet of semiconductors is already delivering on its promises

The reliability of the latest optoelectronic nanocomponents has accelerated their integration into devices that use light detection and control. In reality, the semiconductors that feature these tiny composites operate on bandgap energies ideal for absorbing infrared radiation. In addition, their electrical conductivity is optimal for many applications.

The use of these nanocomponents thus improves the sensitivity of gas sensors, as well as the receptivity of optical detection biosensors.

In addition, new organic light-emitting diode tandem displays have been manufactured. These sophisticated devices stack the red, blue and green components of each pixel in ordinary screens. It then results in much higher image resolutions.
