Improving Solar Cells with Quantum-Dot Microscopy
Researchers working at the National Institute of Standards and Technology (NIST) have developed a new microscopy technique that uses a process similar to how an old tube television produces a picture—cathodoluminescence—to image nanoscale features. Combining the best features of optical and scanning electron microscopy, the fast, versatile, and high-resolution technique allows scientists to view surface [...]
Quantum Dot Solar Breakthrough at University of Toronto
Quantum dots (also known as nanocrystals) have certain electronic properties, which we can use to convert photons (light particles) into electricity in much the same way as with traditional solar cells. Quantum dot solar cells films, are usually built up by much more inexpensive material if compared to crystalline- or thin film silicon, which is [...]
Transparent Polymer Solar Cells Developed at UCLA
In the search for more efficient solar cells, UCLA researchers have developed a new transparent solar cell that points towards the age when windows could become small solar energyfarms without blocking the view. They have developed a new kind of polymer solar cell (PSC) that produces energy by absorbing mainly infrared light (not visible light), [...]
German scientists use nanoparticles to make solar cells more efficient
Apartfrom the high costs of solar cells, their low efficiency is alsohampering their attractiveness. Research on ways to improve theefficiency have been going on for a long time, but not many havepromised a dramatic increase in performance, which might herald a solarrevolution. Scientists at the Institute of Condensed Matter and SolidState Optics at Friedrich-Schiller-Universität in [...]
