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.
Last year at Hannover Fair, lots of people were talking about Industry 4.0. This is a concept that seems to have a different name in every region. I’ve been referring to it as the Industrial Internet of Things (IIoT), not to be confused with the plain old Internet of Things (IoT). Others refer to it as the Connected Industry, the smart factory concept, M2M, data extraction, and so on.
