The biggest new word in solar these days is the littlest—nano. A host of spiffy names describe the newest achievements in creating low-cost,high power, lightweight photovoltaic panels. Quantum dots, nanowires,nanoantenna, carbon nanotubes, and multiple quantum wells, all are atthe heart of this evolution in solar cells. One company has evendeveloped spray-on photovoltaic material using nanotechnology. [...]
In crystalline silicon, the end isn’t here, but it’s coming into view. Silicon solar cells, according to various researchers, will not be able to convert more than 29 to 33 percent of the light thatstrikes them into energy. Realistically, the limit is likely closerto 24 to 25 percent because of factors like heat, said Tom [...]
Here’s a (likely apocryphal) tale told in thethin-film solar manufacturing world: An unnamed CIGS solar startup was doing process development and ranout of the de-ionized water used as a cleaning agent in theirmanufacturing process. That particular day, they substituted straightCalifornia tap water in their process and rather than ruin theirexperiment – the efficiency of the [...]
