Xerox Could Blow Open Concentrating Solar Power Field With New Printer
5 April 2016 | CleanTechnica
by Tina Casey
Concentrating solar tech has been getting the stinkeye from some industry observers, with the main beefs being high complexity and high costs compared to conventional solar panels. Nevertheless, the US Energy Department has made a national showpiece out of five gigantic utility-scale thermal solar power plants, and last year the agency threw some grant dollars at Xerox’ cutting edge PARC company to work on the micro-scale, photovoltaic end of the concentrating solar field. The PARC micro-scale concentrating solar project aims at whittling down both the cost and complexity of concentrating solar power, by integrating tiny hexagonal solar elements directly into a flat panel.
Xerox PARC Working on Cheaper Photovoltaics

The MIT Technology Review reports that researchers at Xerox PARC are working on a digital printing process that could reduce the cost of mass producing concentrated photovoltaic systems. The process could increase efficiency dramatically by using lenses to concentrate the light onto small cells in the panel.
Solar energy is growing in low- and middle-income communities, according to GreenBiz. The organization cites a study from Kevala Research to make the claim.

US Patent Issued...on "Concentrating Solar Collector with Solid Optical Element"

"United States Patent no. 7,906,722, issued on March 15, was assigned to Palo Alto Research Center Inc. (Palo Alto, Calif.) 'Concentrating Solar Collector with Solid Optical Element'. According to the abstract released by the U.S. Patent & Trademark Office: 'A Cassegrain-type concentrating solar collector cell includes primary and secondary mirrors disposed on opposing convex and concave surfaces of a light-transparent (e.g., glass) optical element. Light enters an aperture surrounding the secondary mirror, and is reflected by the primary mirror toward the secondary mirror, which re-reflects the light onto a photovoltaic cell mounted on a central region surrounded by the convex surface. The primary and secondary mirrors are preferably formed as mirror films that are deposited or plated directly onto the optical element. A concentrating solar collector array includes a sheet-like optical panel including multiple optical elements arranged in rows. The photovoltaic cells are mounted directly onto the optical panel, and the primary mirrors of the individual collector cells include metal film segments that are coupled by the photovoltaic cells to facilitate transmission of the generated electrical energy. Bypass diodes are connected in parallel with the photovoltaic cells.'"
