Researchers at the Moscow Institute of Engineering Physics at the National Institute of Nuclear Energy, Russia, have developed a new technology for manufacturing quantum dots, helping to develop cheap solar cells that absorb broad-spectrum sunlight.
The current photoelectric device is based on silicon inorganic semiconductor materials, low efficiency, can not handle all the spectrum, and the cost is expensive.
Quantum dots are the size of a few nanometers of semiconductor crystals that change their size and can easily control the properties of solar cells, such as expanding the absorption spectrum. Quantum point condensate production is done by simple and inexpensive methods, but in order to obtain high quality coatings, Carefully select the production conditions and the organic molecules that link the quantum dots together.
Russian scholars have developed a technology to replace the ligand at room temperature, help to change the distance between the quantum dots, in order to control the efficiency of charge energy transfer, not only for the manufacture of photovoltaic cells or light-emitting diodes, but also can create more complex Of semiconductor structures, such as semiconductor structures used to make highly sensitive new generation sensors.
