"Shadow state" discovery could dramatically boost solar power efficiency
Researchers at the University of Texas say it is admissible to hike the energy yield of solar cells by exploiting what they call a photon's "shadow state", doubling the number of electrons that may be harvested in the process. They exact the discovery could up the theoretical maximum efficiency of silicon solar cells from 31 to 44 percent.
Prior delve into led by chemist Xiaoyang Zhu demonstrated that a theoretical increase in efficiency to as high as 66 percent would be possible if solar cells could be made to additionally procure so-called "hot electrons", residual heat energy that is lost within about a picosecond after a cell absorbs a photon. Zhu then found that this was possible, but only when harvesting photons from "strongly focused" sunlight, impractical in real-world applications.
But the team's latest findings point to an alternate means of boosting efficiency. The organic plastic semiconductor pentacene, when absorbing a photon, creates an exciton (an electron paired with an electron pocket) which is quantum mechanically coupled to a dark "shadow state" multiexciton from which an additional electron can be harvested. This way, a photon provides magnify the electrons. Zhu says that the process could see solar cell efficiency increase to 44 percent without the need for a focused solar beam.

The U.S. Office of Vigour’s (DOE) allow-guarantee program – part of the American Convalescence and Reinvestment Act (ARRA) – has had an undeniably promising carry out on solar enterprise deployment and kit manufacturing in the U.S. However, ARRA qualification requirements have often been a roots of muddle for developers and manufacturers.
Over the ago couple of years, many solar materiel providers have set up betray in the U.S. in require to submit with the ARRA’s Part 1605 Buy American provisions, which insinuate guaranteed family-theme requirements on projects backed by ARRA funding. “ARRA-compliant!” despatch became a blue-eyed span of time in commodity marketing.
Of orbit, under many PV cell and module manufacturers’ around labor models, cell manufacture and module circle may not take flat under the same roof – or even within the same mountains.
U.S.-assembled modules may check cells manufactured at large, and U.S.-manufactured cells may be integrated into modules produced elsewhere. Which types of modules are qualified under the ARRA’s rules? What about surplus-of-system components?...

Blunt nanostructures could make high-efficiency solar cells easier to fabricate
As Luo explained, this finding could greatly improve the light-to-electricity conversion process in solar cells. “A solar cell is an electrical device that converts the energy of light into electricity,” he said. “However, the wavelength of light in

Saita installs PV wastewater treatment plant for Belgian cell producer
The closed-loop system collects and treats both the water from the production process and the water from utility equipment, thus enabling the IWT to achieve recycling levels of 97% of the entire water needs of a solar cell manufacturing plant.

Carbon Nanotubes offer Prospects for Novel Thin-film Solar Cells
In a solar cell the exciton must drift rapidly to another layer in the device where the charge separation occurs but fast reabsorption before separation leads to low efficiencies. Individual CNTs suffer from low efficiency because of this but the LANL

Is solar really green energy? ***a must read***?
First off, Solar Cells are made from Silicon, which sounds inoffensive....
In order to understand how a solar cell works, a little background theory in semiconductor physics is required.
Enchanting link. Also, it should be noted that photovoltaic solar energy is indeed big business. As you commented, the environmental risks are wholly real.
