New research puts us closer to do-it-yourself spray-on solar cell technology

In a 2014 study, published in the journal ("Fully solution processed all inorganic nanocrystal solar cells"), St. Mary's College of Maryland energy expert Professor Troy Townsend introduced the first fully solution-processed all-inorganic photovoltaic technology. While progress on organic thin-film photovoltaics is rapidly growing, inorganic devices...

New electrode gives micro-supercapacitor macro storage capacity

Micro-supercapacitors are a promising alternative to micro-batteries because of their high power and long lifetime. They have been in development for about a decade but until now they have stored considerably less energy than micro-batteries, which has limited their application. Now researchers in the Laboratoire d’analyse et d’architecture des systèmes...

Invisibility cloak might enhance efficiency of solar cells

Success of the energy turnaround will depend decisively on the extended use of renewable energy sources. However, their efficiency partly is much smaller than that of conventional energy sources. The efficiency of commercially available photovoltaic cells, for instance, is about 20%. Scientists of Karlsruhe Institute of Technology (KIT) have now published...
