Researchers at the Rensselaer Polytechnic Institute have created a nano-engineered coating for photovoltaic (PV) cells that increases sunlight absorption to 96.21 percent. Reported in “New nano coating boosts solar efficiency” on CNN.com, this new technology may improve performance of PV by enabling greater energy capture. Importantly, this coating also improves energy absorption for non-direct angles between the sun and PV collector.
Solar reflectivity is only one parameter among a complex array of variables impacting PV performance. Nonetheless, the CNN article suggests that efficient solar energy absorption at high angles may eliminate sun tracking systems, which have parasitic power draws.
Just when you thought mobile technology couldn’t get any more personal, Procter & Gamble have come up with a way to put your mobile where your mouth is, in the form of a Bluetooth 4.0 connected toothbrush.
MCU manufacturers have become excellent sources for information you can use to get a head start on your next design. In addition to the normal data sheets and evaluation boards, MCU manufacturers also often provide complete reference designs -- working designs that establish a proven baseline for creating your own custom design.
