Solar Junction Achieves World Record for Solar Cell Efficiency Using Veeco MBE System

Veeco Instruments (News - Alert), a specialist in thin film technologies, announced that Solar Junction, a provider of solar energy cells, has achieved the world record for energy efficiency of a commercial-ready production solar cell based on Veeco Molecular Beam Epitaxy (MBE) system.


Solar Junction, a developer of high efficiency multi-junction solar energy cells for the concentrating photovoltaics (CPV) market, has used Dual GEN200 MBE cluster-tool design in its solar cell technology.

In October 2012, Solar Junction reported that power conversion efficiency of their CPV cells was measured at an unprecedented 44 percent at 947 suns, as verified by the National Renewable Energy Laboratory (NREL).

According to Homan Yuen, Solar Junction’s vice president of research and development, Veeco’s MBE system enables the company to reach critical milestones in solar cell efficiency. “Their system is instrumental in pushing the boundaries of technology to make CPV a more competitive option for solar power.”

The GEN200 MBE features a flexible cluster tool design that helps the system deliver higher throughput and lower cost per wafer, in a footprint up to 60 percent smaller than comparable MBE systems. The design provides the material source and wafer configuration flexibility for R&D or for multi-wafer production applications.

GEN200 MBE technology can also support dual growth modules, allowing facilities to either greatly increase production or grow different materials within a single, integrated system.

Jim Northup, Veeco’s vice president and general manager, congratulated Solar Junction for its feat, “We wholeheartedly congratulate Solar Junction on their world record, and are committed to supporting their new facility’s production ramp. The GEN200 is the ideal pilot production tool, and we take great pride in providing the deposition platform for this ground-breaking result.”

Veeco delivers solutions to manufacturers of LEDs, power electronics, hard drives, MEMS and wireless chips. The company specializes in MOCVD, MBE, Ion Beam and other advanced thin film process technologies.
