In a paper published in Nature Photonics, University of Toronto researchers report the first efficient two-layer solar cell based on colloidal quantum dots
Scientists have developed an improved preparation process for kesterite solar cells, which resulted in a new European record efficiency of 6.1 percent.
In the harsh, isolated, semi-desert region north of Cairo in Egypt, 150 acres has been planted with beans, peas and orange trees. But there is a problem: an endless need for water. Farmer Tantawi Mostafa explains: “Each plant needs a certain amount of water, depending on the season. Peas, for instance, need a lot of water, I have to irrigate them at least five hours a day. Oranges and…
Researchers are creating a new type of solar cell designed to self-repair like natural photosynthetic systems in plants by using carbon nanotubes and DNA, an approach aimed at increasing service life and reducing cost.
