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/
What happens when utilities meet their state mandates for renewable energy production or offsets?
In the coming years we could run into a schedule, and desirable – from the utilities point of view, loll in Solar. States are canceling, re-assessing, or no longer interested in initiating rebates for renewable energy because utilities have moved to capitalize on the financial benefits provided to them. It has also quieted the calls to speed up adoption of Solar Energy. It is eating its nemesis, alive.
So, what will keep solar alive, absent rebates and offsets? It will be advances is panel efficiency, battery design, and inverter technology.

Here are a few good tools for installers.
GTAT: Will Silicon Carbide Become GT Advanced Technologies’ Next Materials Business? http://m.seekingalpha.com/article/2431505?source=ansh
” It was not that long ago that GT Advanced Technologies (NASDAQ:GTAT) operated exclusively in the solar space. In fact, up until August 2011, GTAT traded under the NASDAQ stock ticker symbol SOLR and was known as GT Solar International. Prior to 2011, GT Solar’s business model consisted strictly of the manufacture and sale of directional solidification systems furnaces and chemical vapor deposition reactors to produce the low cost, high quality polysilicon, the key raw material used in the creation of photovoltaic wafers.”
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.

Sven Armbrecht from LG Solar describes how N-type silicon wafer technology can increase the power efficiency of solar cells and make grid parity a viable prospect – See more
“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.”
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.
