GE sees bright future for thin film solar technology

Niskayuna, N.Y., March 18, 2010 — GE is focusing its research and development efforts on thin film photovoltaic (PV) technology in conjunction with PrimeStar Solar Inc., the startup firm in which GE is a majority investor.

Working closely with PrimeStar technology experts, the company is bringing to bear the full scale of its four Global Research operations to address each of the challenges required to bring a new product to market.

The GE/PrimeStar product is being developed at PrimeStar’s headquarters in Arvada, Colo.

A team of PrimeStar technologists with more than 100 years of combined thin film deposition expertise is working closely with GE researchers, who are focused on several key areas in order to achieve best-in-class technology.

These include device efficiency, reliability, production and installation costs and manufacturability. Hundreds of technologists in Germany, China, India and the U.S. are working on GE solar technologies — addressing these challenges in the following ways:

The team in Munich, at the heart of the global solar power industry, is utilizing world-class indoor and outdoor solar system test facilities where they study finished module performance to identify and address degradation mechanisms and packaging issues.

In addition to the focus on the module itself, this team also brings deep expertise at the system level. This allows them to define system-level optimized features and metrics for the module.

In China, where most of the world’s CdTe raw materials are found, researchers at GE’s China Technology Center in Shanghai are focused on CdTe materials and the impact they have on device performance.

Improving material quality and developing advanced materials characterization techniques are key topics being addressed by the Shanghai team.

In India, GE is leveraging extensive modeling capabilities at its John F. Welch Technology Centre in Bangalore. Unlike the exclusively experimental approach favored by many in this field, GE believes that dramatic improvements in the device performance and reliability will be realized through a deeper understanding of the materials and basic physics of the device. The team in Bangalore is tasked with building comprehensive models to help guide advanced device design.

Finally, GE’s research team in Niskayuna, N.Y., is working on all facets of CdTe module development, including material growth, device development and robust process development.

GE currently provides a range of utility-scale solar solutions, including smart grid power electronics and pre-packaged systems. GE’s Brilliance solar inverter offers reliable power conversion technology derived from its 1.5 MW wind turbine.
