Concentrated photovoltaic cells with 43.5% efficiency commercially ready
The cell’s efficiency was confirmed by NREL’s Measurement and Characterization Laboratory. The 5.5 x 5.5 mm production cell tops the current record by 1.2 percent and is significantly higher than the average efficiency gain achieved by previous record holders, claims the company.
The Solar Junction cell measured a peak efficiency of 43.5 percent at greater than 400 suns and still maintained an efficiency as high as 43 percent out to 1,000 suns. Solar Junction’s cells incorporate the company’s proprietary adjustable spectrum lattice-matched A-SLAM technology, which enables the company to more optimally partition the solar spectrum for maximum efficiency and greater reliability.
Increases in CPV cell efficiencies are a key driver for improving CPV economics, with each cell efficiency gain leveraged and multiplied in value by the components that account for the remaining 80 percent of total system costs.
