Solar panel windows: coating of quantum dots on windows harvest energy from the sun - TomoNews

LOS ALAMOS, NEW MEXICO — Researchers at the Los Alamos National Laboratory in New Mexico have developed a film of quantum dots that can turn windows into photovoltaic systems. Quantum dots can be used as semiconductors. According to IEEE Spectrum, they consist of a CdSe inner core, a Cd1−xZnxS outer shell and a silica coating that prevents them from oxidation. The quantum dots are spead into a thin sheet that can be placed onto a glass window pane. When photons from sunlight hit a quantum dot, it sends the electron in the valence band into the conduction band, leaving a hole behind. When the electron recombines with the hole in the valence band, a new photon with lower energy is generated. This new photon propagates within the glass via internal reflections. Energy is then generated when the propagating photons reach the window frame, where solar cells are stored. The coating of quantum dots can be used on any window and to turn it into a sunlight harvesters at costs lower than are currently available. The study was published in Nature Energy on Oct 10. ----------------------------------------­--------------------- Welcome to TomoNews, where we animate the most entertaining news on the internets.

why on a window? just roll that shit over the whole roof,idk
Heidi JB (2 years ago)
Donald Sanders why would you want it on a window as opposed to the roof or siding? simple question, I under that it is a self contained unit so that's good too....but I just for see issues with seeing out the window long term, or if it fails, you replace the entire pane, etc. why would you want it on glass. if you can't answer, iguess...

eg0zb yes the see thru part is kick ass

Heidi JB What part don't you get, "Solar" or "Window"
eg0zb (2 years ago)
the point is that you can see through

Wow that is cool

Yeah I was thinking a same kind of thing but with double layer glass, water and some kind of things inside that collect the power and could be adjustable some how (the harvester would flow in the water) so you could use them as blinds or just darken the room a bit...

🤔 hope do good savings on power bills
Nate D. Higgers (2 years ago)
true but in case SHTF and there is no power available it makes a lot of difference
