year, and is expected to ship 22MW in 2010. The company’s products are designed for utili- ties and independent power producers to use in industrial scale deployments such as large- scale rooftop and ground mount installations.


JDSU Unveils CPV Technology for Solar Power Generation


The firm is introducing its multi-junction solar cell technology to provide highly efficient and cost effec- tive solutions for solar system integrators


JDSU has announced the availability of concentra- tor photovoltaic (CPV) cells that are designed to capture concentrated sunlight within solar panels for electrical power generation.


The company is working with leading solar system integrators that will use its CPV cells in solar mod- ules installed at power generation facilities world- wide.


Concentrated photovoltaics use a cost effective technology that is emerging as one of the ideal solutions for solar power generation. According to the “CPV Industry Report 2010,” CPV system instal- lations in the US will represent $70 million in 2010 and are expected to grow to more than $3 billion by 2015.


The CPV market is initially being driven by use in power plants at college campuses, shopping cent- ers and industrial buildings that generate power in the 500 kilowatts (kW) to 10 megawatts range, com- pared to residential roof-top housing market installa- tions that use about 5kW per home.


“Electrical power needs will skyrocket over the next twenty years, requiring new forms of power genera- tion that are more efficient, affordable and envi- ronmentally friendly,” said Alan Lowe, president of Communications and Commercial Optical Products at JDSU. “The CPV cell from JDSU brings a viable technology to the solar market that leverages our strong history of semiconductor experience and volume manufacturing expertise.”


“Initial demonstrations of CPV technology have proven successful and now larger projects are start- ing to ramp,” said Greg Sheppard, chief research


officer at analyst firm iSuppli. “CPV installations will represent 100 megawatts in 2011 and we expect that number to grow to one gigawatt by 2015. CPV will have a particular advantage in sunny regions, such as in the desert, over other solar technolo- gies.”


JDSU CPV cells are optimized to capture different parts of the sun’s spectrum in multiple junctions, resulting in conversion efficiencies approaching 40 %, an ideal range for solar system integrators. The CPV cells are specifically designed to capture con- centrated sunlight at 500 to 1,000 times its original power. Additional benefits include a small footprint, improved temperature performance, less use of semiconductor materials, and lower cost per kW compared to other photovoltaic technologies.


In addition to its new CPV technology for land installations, JDSU has been providing solar power products to the satellite industry for several dec- ades. The firm also provides photovoltaic solutions for the digital monitoring of smart grid power plants.


The Solar Shakeout: Who Will Thrive, Survive, or Dive?


Lux Research says that Q-Cells subsidiary Solibro and start-up Miasolé are dominant innovators in CIGS technology. Furthermore, Amonix has broken away from its competitors followed by Concentrix and Solaria, while the rest of the CPV field struggles.


Despite a strong opening to 2010 for the solar market, manufacturers are now bracing themselves for further price declines and stiffer competition according to Lux Research. Lux Research provides strategic advice and on-going intelligence for emerging technologies.


As module makers prepare for a renewed trench war based on production scale, inverter players aim to stake their competitive territory based on performance improvements and novel architectures.


The new report entitled “Sorting Solar Module and Inverter Manufacturers on the Lux Innovation Grid” assesses the likely winners and losers in the renewed solar shakeout. It analyzes the competitiveness of module-makers in crystalline silicon (x-Si), thin-film silicon (TF-Si), cadmium
