Quantum Dot, a semiconductor whose crystals are nano-sized has already made a lot of impact in nanotechnology. In the case of solar cells, quantum dots are used as an absorbing photovoltaic material. Q dots are the focus of a new research field in rapid evolution, with the promise for applications in solar cells, transistors and lasers, all at high efficiency, among other things.

The points have the advantage of having a bandwidth which can be adjusted by simply changing the size of the nanoparticles, so that they can be easily designed in way to take up different areas of solar spectrum. This makes them very attractive for multi-junction solar cells; you could use a series of quantum dots of different sizes next to each other to absorb different parts of the spectrum.

Basically, it would significantly reduce the cost and complexity of manufacture of such cells. You can buy quantum dots from several vendors who have already established a big market online. There are several grades and quality you can choose from.

The cheapest option is still the cells to single junction quantum dot. Even here, the use of quantum dots has certain advantages. Because the bandwidth can be adjusted at will, a single junction cell can be made to absorb light in the far infrared, which is half of the Sun's energy. So far, the record efficiency for a solar cell quantum dot is only 9%, which is approximately half the performance of current commercial cells silicon. However, this is a new area in which progress has been both stable and fast.

A better point to understand why to buy quantum dots

As in conventional solar cells, the cells use CQD p-type semiconductor to handle the load and generate electricity. However, the semiconductor quantum dot n-type tend to bond with oxygen atoms, leaving its electrons and turning into p-type, obviating the cell. Type semiconductor n fabricated using flexible materials are notoriously susceptible to oxidation after a few minutes exposed to air.

New type of material n-type DQA is used along with lead sulphide which does not bind with the oxygen, preserving the cell performance and opening to a world of new optoelectronic devices that capitalize on the best light and electrical properties, including better communications satellite and pollution detectors. Buy quantum dots online to understand the large variety and quality.

Although 8% efficiency is much less than the commercially available panels, solar cells finally quantum dots have the potential to be more effective than their silicon counterparts, because a single photon can be made to excite several electrons within the cell. Make sure to buy quantum dots only from reputed dealers.

Purchase quantum dots for incorporating to quantum communication

Quantum communication technology represents a new mode of communication to be completely safe and allows high-speed data exchange as vectors of information carriers are photons.

Quantum communication is based on the quantum key distribution technology (QKD); data are encrypted using encryption keys carried by quantum particles as polarized photons. Using photons to circulate the information would allow high-speed data exchange and could be used through the existing fibre infrastructure.
