Up to 37% Efficiency Under Concentrated Illumination
Emcore's Triple-Junction Heritage InGaP/InGaAs/Ge solar cells with n-on-p polarity are built on germanium substrates and incorporate a multi-layer antireflective coating which 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 1200 Suns) and high current densities.
