This new solar glitter [Sandia] can help a lot in energy sector. Solar systems made of tiny solar cells as small as a grain of sand could be the next generation in inexpensive solar energy options.
The tiny cells of the micro-systems enabled photovoltaic system have an efficiency of as much as 20 percent, & cost only $1.80 per watt peak as compared to $4 per watt peak in conventional systems. They can be mounted on a flexible material such as clothing or curtains, & many of the manufacturing techniques are already in place.
The tiny solar cells will also work more efficiently in partial shade, since each cell is separate. Solar cells do not function if any part of them is in shade.
Sandia researcher Greg Nielson, team leader on the Micro-systems Enabled Photovoltaic cell project, holds up a sample of the cells that won a regional Excellence in Technology Transfer Award from the Federal Laboratory Consortium.
