Key to the innovation is a mesh solar panel, which allows air to enter the battery, and a special process for transferring electrons between the solar panel and the battery electrode. Inside the device, light and oxygen enable different parts of the chemical reactions that charge the battery. http://news.osu.edu/news/2014/10/03/batteries-included-a-solar-cell-that-stores-its-own-power/
Though often lumped together under the term “energy storage,” the field is in fact a wide range of technologies ranging from well established to speculative, each with different functions, advantages, and drawbacks. The discussion below focuses on existing grid-scale (greater than 1 MW rated power) projects and is generally ordered by level of deployment.
SNL is seeking proposals from commercial partners who would like to invest in the development of new solar thermal technologies and/or validation of their technological concepts using SNL’s expertise and infrastructure. Together, we intend to create or improve solar thermal technologies applicable to US manufacturing or deployment. Utilizing EERE-provided funding, SNL will match 30% of the Sandia labor costs for selected proposals for a period of up to two years.

“Solar Frontier’s new 20.9% efficiency record resulted from a CIS cell cut from a 30cm by 30cm substrate produced using a sputtering-selenization formation method – the same method we use in our factories. The significance is twofold: it ensures we can transfer our latest achievement into mass production faster, and it proves the long-term conversion efficiency potential of Solar Frontier’s proprietary CIS technology,” said Satoru Kuriyagawa, Chief Technology Officer of Solar Frontier. “Solar Frontier has entered into the next phase in the development of CIS technology, and we look forward to building on this achievement and driving our efficiency even higher.”
“A novel visible-light-absorbing dilute alloy, Ga(Sbx)N1−x is synthesized by metal organic chemical vapor deposition (MOCVD) for solar hydrogen production. Significant bandgap reduction of GaN from 3.4 eV to 1.8 eV, is observed with a low (2%) incorporation of antimonide, as well as the lattice expansion are in agreement with our first-principles calculations. The band edges of Ga(Sbx)N1−x are found to straddle the water redox potentials showing excellent suitability for solar water splitting.”
Power generation, currently, is equivalent to rubbing two sticks together. We need to start viewing it as a technology, because more and more the electricity demand will come from technology – smartphones, smart TV, smart appliances, and smart cars, leading to a mature smart grid that will regulate how hard we run those two sticks together.
Communication companies can teach the electric utilities a thing or two about attacking a declining customer base: separate entities for residential and commercial.
Note to come as I research this theory.
Remote Solar Isolator The Remote Solar Isolator is able to remove all lethal voltages on any solar array providing safe access for all emergency services. it stops the combining of solar panels whenever the grid power is removed.
The race to be #RenewablyRelevant is on, although Tesla has already made the first move. Who’s next.
