Solar Junction Raises Standards with 40.9% Efficiency

NREL tested the firm’s III-V standard solar cells manufactured in Solar Junction’s California-based facility and confirmed this result.

The National Renewable Energy Laboratory (NREL) has verified that Solar Junction’s III-V standard multi-junction concentrated photovoltaic (CPV) based solar cell has 40.9% efficiency.

The cells tested were manufactured entirely in-house on the Solar Junction production line operating in San Jose, California.

“This verification from NREL of our standard, commercial-ready 5.5 mm triple junction cell, which is the dominant cell size integrated into CPV systems, validates the results that we have been seeing in-house, as well as the reports we have received from our customers,” states Jim Weldon, CEO, Solar Junction.

The cells were submitted in September for testing at NREL as part of Solar Junction’s SAI Incubator Grant. Solar Junction is in an efficiency ramp mode with its terrestrial-optimized cells and expects to see continual cell efficiency improvements as the company tests its newest and most advanced cells with its extensive in-house test and characterization capability.
