Xunlight Featured as One of America’s Most Promising Startups

Xunming Deng and Liwei Xu left Nanchang, China, 25 years ago to begin graduate studies at the University of Chicago—Deng in physics and Xu, his wife, in chemistry. What they've accomplished since receiving their PhDs may be more exceptional: They've established a green-energy company in Toledo, Ohio, in the middle of America's struggling automotive manufacturing belt.
Toledo Tries to Overcome Rust-Belt Image

The glass is half full again in Toledo. The Ohio city once known as the glass-making capital of America is trying to forge a new identity as a solar energy, green jobs metropolis of the future.

Once the glass-making capital of the country, most of the city’s output over the years has gone into making everything from windshields to windows for cars and buildings.

Like his uncle, his grandfather and many of their neighbors, Arie Versendaal spent decades working at the Maytag factory here, turning coils of steel into washing machines.
Toledo Finds the Energy to Reinvent

This city became famous in the last century for being one of North America’s leading glass centers

Xunlight Corporation is at the forefront of innovation and advanced photovoltaic module manufacturing technologies. The company’s principal PV products are flexible and lightweight and utilize various thin film silicon-based alloys, including amorphous silicon (a-Si), amorphous silicon germanium (a-SiGe), and nanocrystalline silicon (nc-Si). These solar cell alloys are deposited on a thin stainless steel substrate and then encapsulated in flexible lamination polymers to complete the module design.

Products with two different device structures are produced at the company’s manufacturing facility in Toledo, Ohio. These include:

· a-Si/a-SiGe/a-SiGe triple-junction (TJ) solar cells - Currently Available

· a-Si/nc-Si multiple-junction (micromorph) solar cells

Xunlight Corporation’s academic partner, Dr. Xunming Deng’s Thin Film Silicon Photovoltaic Laboratory at the University of Toledo (UT), maintains the world record for efficiency of single-junction a-Si based solar cells. This is an important world record since it is a record for the most inexpensive type of silicon-based solar cells. Dr. Deng and his associates (students, postdoctoral researchers, and visiting scholars) at UT utilize a low-germanium content a-SiGe material and a specially designed p-type semiconductor layer for its solar cells; achieving single-junction solar cells with ~13% initial efficiency and 10.4% stabilized efficiency.
