What are quantum dotted solar cells?

Sun cells Quantum dots are solar cells built on a network of crystals made on a nanometer scale that have the potential to overcome conventional solar cell technologies due to the basic reduction of how solar cells capture sunlight. The standard solar cell is built on a layer of material that is most effective when capturing one particular band or wavelength of light. However, quantum dots in a quantum dot of solar cells can be created to capture more light strips by changing their size and chemical makeup in the production process. As a result, a number of different types of quantum dots on one layer of substrate, which is able to capture a wide range of light wavelengths, which makes it much more efficient and economical than standard solar cells.

Technical limit for converting sunlight into electricity with solarThe article composed of one type of chemical structure is theoretically a maximum of 31%. However, commercial solar cells since 2011 have a practical level of efficiency of 15% to 17% at their maximum level. Research has been conducted for decades to find improvements to solar cell technology from several bargain points, such as a reduction in the cost of photovoltaic material based on highly pure silicon by replacing a flexible polymer and metal substrates. Research of solar cells also focused on capturing the wider range of band light, both on stacking different layers of solar materials or engineering unique crystals known as quantum dots, on one layer of solar cells. All approaches have their disadvantages and quantum dot solar cells also try to take advantage of their advantages if possible.

The resulting technology of quantum dot solar cells is based on the physics and chemistry of quantum dots themselves, but also includes the principle of multilayer solar cells andThe ability to act these components into a more easily processed, potentially flexible substrate. Ideally, this technology focuses on the production of so -called so -called sunlight with full spectrum, capable of capturing up to 85% of the radiant, Visible Light and converting it to electricity and also capturing some light in infrared and ultraviolet belts. Energy outputs for such solar cells have achieved 42% in the laboratory since 2011 and the current effort includes finding practical, cost -effective chemical structures for such technology that it can be produced in bulk.

The

approaches to the new generation solar articles focused on the model of three belts or a multi-tuning model where different layers of the Gallium-Arnenid-Nnit Walk alloys are interconnected. Another chemical composition with multi-junction used zinc-mangansko-tellurium alloy and quantum dot solar cells are also made from cadmia-sulphide on the dioxide substrate, which is covered with organic molecule to connect metal subStray and quantum dots. Other variations on three layers of belts include research using Indium-Gallium-phosphide, Indium-Gallium-Armenid and Germanium. Many chemical combinations seem to work and it seems that the size of the molecules used in process, such as an organic interconnection layer, has a greater direct impact on the efficiency of quantum dot solar cells to capture a wide range of light than the real chemistry of the materials themselves. However, layers in a multi-tuning solar cell, including quantum dots themselves, often have to be less than two nanometers strong, which requires an extremely fine level of accuracy to create only a microchip fabr, creating computer processors and memory.

The aim of the research of quantum dot solar cells is to increase the production of solar cells more efficient and cheaper. Ideally, they will be built on flexible polymer materials so that they can be painted on buildings or used as a coatingOsna electronics. Then they would also be able to weave synthetic fabrics for clothing and upholstery in cars. This would provide solar cell technology of extended application in electrical creation, which could complement or replace the need to use fossil fuels for many common consumers' needs, including climate control, telecommunications, transport and lighting. Such solar cells were created in the laboratory in the US, Canada, Japan and other countries, and the first company to find the method of cheap mass production of this technology is likely to capture the world's unprecedented market.
