Quantum Dot Solar Windows Go Non-Toxic, Colorless, With Record Efficiency
“A luminescent solar concentrator is an emerging sunlight harvesting technology that has the potential to disrupt the way we think about energy; It could turn any window into a daytime power source.”
Nanowire-based Solar Cells
“Excitonic solar cells – including organic, hybrid organic-inorganic and dye-sensitised cells (DSCs) – are promising devices for inexpensive, large-scale solar energy conversion. The DSC is currently the most efficient and stable excitonic photocell. Central to this device is a thick nanoparticle film that provides a large surface area for the adsorption of light-harvesting molecules. However, nanoparticle DSCs rely on trap-limited diffusion for electron transport, a slow mechanism that can limit device efficiency, especially at longer wavelengths.”
Glowing Nanomaterial To Drive New Generation Of Solar Cells
“Physicists have discovered radical new properties in a nanomaterial which opens new possibilities for highly efficient thermophotovoltaic cells, which could one day harvest heat in the dark and turn it into electricity. The research team has demonstrated a new artificial material, or metamaterial, that glows in an unusual way when heated.”
