Los Alamos National Laboratory researchers have developed new quantum dot solar cells that match the efficiency of existing quantum-dot based devices, but without lead or other toxic elements relied on by most solar cells of this type. Victor Klimov, a physicist specializing in semiconductor nanocrystals at Los Alamos and lead author of the report featured […]

University of Zurich researchers have developed a new type of nanoparticle for novel use in artificial photosynthesis by adding zinc sulfide on the surface of indium-based quantum dots. These quantum dots produce clean hydrogen fuel from water and sunlight – a sustainable source of energy. They introduce new eco-friendly and powerful materials to solar photocatalysis. […]

National Renewable Energy Laboratory (NREL) scientists have developed a proof-of-principle photoelectrochemical cell capable of capturing excess photon energy normally lost to generating heat. Using quantum dots (QD) and a process called Multiple Exciton Generation (MEG), the NREL researchers were able to push the peak external quantum efficiency for hydrogen generation to 114 percent. The advancement […]

MIT researchers have now demonstrated solar cells so thin, flexible, and lightweight that they could be placed on almost any material or surface, including your hat, shirt, or smartphone, or even on a sheet of paper or a helium balloon. Such a technology is the thinnest, lightest solar cells ever produced. The new process is […]

Recovery and harvest of heat is the conservationist’s best route to reduce energy consumption.  The amounts of energy that escape use via heat is a stunning number and the heat available from solar and geothermal are huge resources.  When a new technology shows up, even if it’s at the first bright idea stage, we want […]
