Quantum Dots in solar cells: the ideal combination
It seems that Quantum technology Dots on televisions is not the only way to take advantage of its great virtues.
In this sense, quantum dots are having a greater participation in the use of a natural and renewable resource such as solar energy. Everything, through solar panels that have been taking leaps and bounds for some time.
The tests are promising
One of the factors that promotes the high efficiency of QD technology is its combination with a mineral known as perovskite.
The latter has already been part of solar panels for a long time, especially thanks to its ability to absorb light waves.
But, now with the implementation of quantum dots, greater stability has been achieved in combination with perovskite. In effect, it results in a much more stable and efficient solar cell when it comes to producing energy.
Thanks to the tests carried out by EPFL engineers with the support of the Korean Energy Research Institute, they verified its efficiency.
Specifically, figures were discussed that reached almost 26% in terms of efficiency and conversion of light halos into energy.
Its potential is seen in the fact that these figures were obtained only in preliminary tests, without fully developing the quantum dots.
How do Quantum Dots work in solar panels?
Research professionals have made sure that quantum dots are made of tin oxide. The reason: to optimize the transfer of electrons and increase efficiency.
In essence, to measure the efficiency of solar cells, what is taken into account is their ability to capture light rays. That way you can do a much larger energy conversion process in less time.
This is where Quantum Dots technology comes in solar cells, due to its great conduction capacity.
Basically, they are defined as tiny sized particles that are semiconductors of electrons. This has allowed them to be used in televisions, especially due to their ability to emit colored lights after receiving ultraviolet light.
The future of solar energy
Solar energy is a technology that has not yet made the big leap, especially due to the efficiency problems attributed to it.
And it is that, with their current operation, the energy they give off in the form of heat is much more than what they produce.
At this point, quantum dots may represent the future of solar panels, mainly due to their greater light absorption capacity.
However, we still have to wait for more tests in which the perovskite can be stabilized and quantum dots fully implemented.
Even so, it is still a technology with great potential that allows it to go beyond the sun's rays as the main source of energy.
