Technologies and highlights the opportunity that exists in China for HCPV systems. Construction of the power station started in November 2010 and was completed this month, clearly demonstrating the ease and speed with which HCPV systems can be deployed for utility scale solar energy projects.
Cyrium’s portion of the project received support from Environment Canada’s Asia Pacific Partners (APP) program, as part of the Canadian government’s effort to bring Canadian and China based companies together to foster cross-border collaboration on cleantech projects.
During the opening ceremonies, Counsellor of the State Council, Chairman of National Energy Expert Advisory Committee, the former Director of National Energy Bureau Xu Dingming, congratulated each of the project’s contributors on the success of the power plant and requested the parties continue to work toward China’s cleantech effort by accelerating the development of China PV power. In his speech, Wu Dacheng, Deputy Director of China Photovoltaic Society, recognized the advanced nature of the power station, and commented that he foresees a bright future for the development of HCPV in China.
HCPV is considered to the 3rd generation of PV technology making use of low cost, light- concentrating optical systems and group III-V semiconductor materials for the solar cell.
The photo electric conversion efficiency is 2 times more than silicon technology and requires significantly less land area than other technologies for deployment. It also has the highest possibility of reducing power generation cost to level of using coal, which is of considerable importance in China. The completion of this 200KWp project is a signature event in moving China towards greater deployment and application of HCPV systems to meet its rapidly growing energy needs.
Cyrium’s patented nano-technology significantly increases photovoltaic solar cell performance at high concentration. The firm has achieved cell efficiencies of greater than 40%.
Cyrium’s QDEC product line is designed to deliver the highest possible conversion efficiencies which in turn enable CPV systems companies to achieve the lowest levelised cost of energy (LCOE).
Suntrix, headquartered in Shanghai, China, provides HCPV systems for utility- scale and rooftop applications. The SCPV-500, its HCPV panel with the concentration ratio of 576, has been in mass production and deployed at different locations in China.
HelioVolt Solar Modules Lead Environmental Performance
The CIGS solar module manufacturer’s monolithic thin film products have been independently tested by NREL who has confirmed a conversion efficiency of 11.8%.
HelioVolt’s first commercial solar modules have completed rigorous accelerated lifetime testing, with results showing degradation rates one to two orders of magnitude lower than typical module performance required to pass UL and IEC certification.
The next generation thin film photovoltaics are based on HelioVolt’s proprietary copper indium gallium di-selenide (CIGS) manufacturing process designed to produce high efficiency modules. The National Renewable Energy Laboratory (NREL) recently confirmed the company’s conversion efficiency of 11.8% for its monolithically integrated 1.2 x 0.6 meter module size (current HelioVolt cell efficiencies range between 14 - 15%).
HelioVolt said it has invested considerable resources to provide industry-leading module reliability and field performance. The products demonstrate a new benchmark required to maximize energy generation over the module’s lifetime, providing the lowest possible ¢/kWh energy cost.
“First Solar has shown that thin-film modules can deliver utility scale solar power at a compelling cost”, said Jim Flanary, HelioVolt’s CEO and former First Solar COO. “As the next generation of monolithic thin film products enters the market, we need to continue to build on the high efficiency and low-cost promise of CIGS and drive towards higher field performance and higher reliability standards.”
In addition to the rigorous accelerated lifetime testing that HelioVolt modules undergo, the
