Recently, a research team from the Engineering Department of the University of Toronto in Canada has used a type of nanoparticle to increase the efficiency of solar panels by 35%. The main members of the research team are Prof. Ted Sargent and Dr. Susanna Thon. It is reported that the research team mainly uses a type of nano-particles to improve the efficiency of using colloidal quantum dots in solar concentrators.
During the experiment, the researchers used a plasma nanoparticle that controls light absorption. In addition, they also embedded the gold nanoshells directly into the thin films absorbed by the quantum dots.
The researchers said that Golden Nano is not their first choice, given their expensive prices, they hope to find cheap materials that can replace it in the near future.
Through this technology, the research team successfully increased the utilization of solar panels by 35%.
Thon pointed out that the use of colloidal quantum dots has two advantages - first, its cost is very cheap; second, and most importantly, the researchers just by changing the size of quantum dots, you can change the solar cell The absorption spectrum of the plate.
