EMCORE Corporation offers a broad portfolio of compound semiconductor-based optical components and systems for the telecommunications, broadband, broadcast, defense & homeland security, satellite and solar power markets.

Typical Performance of 39% Efficiency Under
Concentrated Illumination

EMCORE's Concentrating Triple-Junction (CTJ) solar cells with n-on-p polarity are built on germanium substrates and incorporate a proprietary antireflective coating, that provides low reflectance over a wavelength range of 0.3 to 1.8µm. These high-efficiency Solar Cells are characterized and optimized for terrestrial applications under concentrated incident illumination (Up To 1500 Suns) and high current densities.
