Subsequent to the establishment of Suncore, the company will commence work on the production of 12-MW of CPV systems for San’an’s current customers and 2-MW of CPV components for projects sourced by Emcore. In addition, Emcore and San’an are aggressively pursuing multiple CPV project opportunities, including the 280-MW solar energy plan in six western regions of China recently announced by the Chinese government.
San’an claims to be the largest producer of LED chips and epitaxial wafers in China and is also a leader in CPV manufacturing and deployment in China. Listed on the Shanghai Stock Exchange, San’an has a market capitalization over US$ 3 billion. In conjunction with the formation of this joint venture, Emcore has agreed to grant Suncore an exclusive license to manufacture Emcore’s current and future improved CPV receivers, modules and systems in China for terrestrial solar power applications.
“The formation of this joint venture represents a significant step in Emcore ‘s business strategy towards introducing CPV products for terrestrial solar power applications in one of the fastest growing solar power markets,” said Hong Q. Hou, President and CEO of Emcore.
“By commercializing Emcore ‘s terrestrial Gen-III CPV systems through this low-cost manufacturing base, we believe Emcore will be in position to gain significant advantages over competing terrestrial solar technologies. Furthermore, the joint venture provides an ideal platform to penetrate China’s emerging renewable energy market.”
“We are very pleased to team up with San’an, a well established Chinese company that shares the same vision and passion for the CPV market,” added Hou. “Our joint venture with San’an will enable Emcore to leverage our existing resources, infrastructure and market presence to accelerate growth in the China and other global markets.”
“China is accelerating development and deployment of solar energy resources,” said Xiucheng Lin, Chairman of the Board of San’an. “The potential for CPV terrestrial systems over the next several years is enormous. Combining the advantages provided by San’an and Emcore, the joint venture will have the capability of high-volume and low- cost manufacturing, the most advanced CPV

technology and continued innovation. Suncore will play a key role in accelerating the market adoption and deployment of CPV solar power. I am very excited for the opportunities that lay ahead for this partnership with Emcore.”
Nagoya’s GaAs based Cathode Brightens View of Magnetism
Nagoya University researchers have created an ultrabright source of spin-polarized electrons using a GaAs/GaAsP cathode to observe the growth of magnetic materials.
Advances in electronics and computer technology are becoming increasingly dependent on our understanding of magnetic materials. The growth of these materials can now be imaged in real time thanks to the work of a team of researchers in Japan led by scientists from Nagoya University.
The researchers took a well-established technique, spin-polarized low-energy electron microscopy (SPLEEM), and refined it to be able to take snapshots of a magnetic material in just a fraction of a second. SPLEEM probes the properties of a material by bombarding a sample with a stream of spin-polarized electrons, allowing the magnetic properties of a material to be measured with a resolution of just 10 nanometers. However, a single SPLEEM image can take up to 10 seconds to acquire. The key to extending the technique to real-time imaging was the development of a brighter electron beam with higher spin purity.
