INCHEON, South Korea—Researchers at Incheon National University have developed a cost-effective, eco-friendly technique for making high-efficiency chalcopyrite solar cells. 

They achieve this by removing residual organic metal-binding ligands from the transition metal oxide thin films, enhancing device stability and performance.

It’s not unusual to find alternative lifestyle activities on or around college campuses. But, at Georgia’s Kennesaw State University, the word “alternative” refers to new types of energy systems.

NORCROSS, GA—Solar cell manufacturer Suniva Inc. will invest nearly $100 million to expand its headquarters here, creating up to 500 jobs. The project will triple manufacturing capacity at the facility.

STANFORD, CA—Researchers at Stanford University have increased the efficiency of a low-grade silicon solar cell by applying relatively cheap crystalline material, perovskite, on top of it.

PITTSBURGH—PPG Industries’ industrial coatings business has received a $2.1 million award from the U.S. Department of Energy to help design and pilot an automated assembly process for photovoltaic modules.

BEDFORD, MA—Solar wafer manufacturer 1366 Technologies has opened the doors of a new 42,000 square-foot assembly plant here. The facility will employ 100 people.
