Graphene as a front contact for silicon-perovskite tandem solar cellsFri, 02 Oct 2015 11:35:51 EDT
A team of researchers has developed an elegant process for coating fragile perovskite layers with graphene for the first time. Subsequent measurements show that the graphene layer is an ideal front contact in several respects. Organics energize solar cell researchThu, 01 Oct 2015 20:50:47 EDT
Scientists are using a new supercomputer to advance next-generation solar energy technologies by probing the functional interfaces found in organic and hybrid solar cells. Invisibility cloak might enhance efficiency of solar cellsWed, 30 Sep 2015 11:04:29 EDT
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 percent. Scientists of Karlsruhe Institute of Technology have now published an unconventional approach to increasing the efficiency of the panels. Optical invisibility cloaks guide sunlight around objects that cast shadows on the solar panel. Finding a way to boost efficiency of CIGS solar cellsMon, 28 Sep 2015 10:30:56 EDT
Researchers have revealed the structure of the buffer layer in a CIGS (copper-indium-gallium-selenide) solar cell at SPring8, the world's largest third-generation synchrotron radiation facility. They found that the buffer layer was composed of two layers: an upper Zn(OH)2 layer and a lower Zn(S, O) layer. By removing the upper Zn(OH)2 layer, the solar conversion efficiency was doubled. New research puts us closer to DIY spray-on solar cell technologyMon, 28 Sep 2015 08:31:19 EDT
A new study puts us closer to do-it-yourself spray-on solar cell technology—promising third-generation solar cells utilizing a nanocrystal ink deposition that could make traditional expensive silicon-based solar panels a thing of the past.
