China Technology Development Group Corp., a clean energy group focused on bringing together related technologies to create solar energy systems, announced today a cooperative agreement between China Technology Solar Power Holdings Limited (CTSP), and the United Nations Industrial Development Organization International Solar Energy Center for Technology Promotion and Transfer (ISEC-UNIDO). This agreement will co-establish the International Photovoltaic Application Laboratory (PV Lab) in Lanzhou, Gansu province on Nov 14, 2009.

CTDC, whose major shareholders include one of China’s leading state-owned conglomerates, China Merchants Group (CMG), and Beijing Holdings Limited (BHL), the biggest offshore subsidiary created by the Beijing Municipal Government, entered into a Stock Purchase Agreement with CTSP earlier this year (on Oct. 27) to gain 51-percent equity interest. CTSP develops and operates large-scale solar plants, such as the grid-connected Delingha 100MW Solar Power Project, making it a natural addition to CTDC’s structure.

The PV Lab will utilize the Delingha installation as a

China Technology Development Group Corp. is an integrated clean energy group focused on solar energy products and solutions in China. The company today announced a Stock Purchase Agreement with China Technology Solar Power Holdings Ltd. (CTSPHL Group) in which CTDC will become the majority shareholder of CTSPHL Group by acquiring a 51 percent equity interest in the company.

Operating through its subsidiary, CTSPHL Group is developing a 100MW grid-connected solar power plant project in Delingha City of Qaidam Basin in Qinghai Province, Northwestern China.

Per today’s announced agreement, CTDC and CTSPHL Group will work together to develop the Delingha 100MW Solar Project, a collaboration that CTDC says it believes will help it reach its goal of becoming an integrated solar company engaged in the design, building and operation of solar power plants.

“We are very pleased to become a controlling shareholder of CTSPHL Group. This marks a significant step that CTDC has

Commercial production has begun for the Sno2 solar base plate used as an electrode element in thin-film solar cells. China Technology Development Group Corporation (NASDAQ: CTDC) said their plant in Xiamen, China started producing the conductive element to solar cells on Sept. 1. CTDC’s first SnO2 production line expects to produce about 70,000 to 80,000 plates per year once the facility reaches full capacity.

“SnO2 base plate is a type of TCO substrate, which is the key upstream component for a-Si thin-film solar cell to maximize its efficiency,” said a company news release. “In recent years, the photovoltaic industry production has been expanding so fast with yearly growth rates over the last five years [averaging] more than 40 percent.”

Recent improvements include the adoption of a new heating process, which allows the product to meet international standards of high transmission, good conductivity and high-haze to help trap light into the amorphous silicon
