PARIS - Compound semiconductor vendor Emcore Corp. (Albuquerque, New Mexico) announced it has signed a $6 million contract with Ball Aerospace & Technologies Corp. (Boulder, Colorado) to design, manufacture, test and deliver solar panels for a new spacecraft. Emcore’s ZTJ space solar cell features and characteristics
Under the terms of the agreement, Emcore said the solar panels will be populated with its third generation ZTJ triple-junction solar cells with n-on-p polarity built on a 140-µm uniform thickness Ge substrate.
. Lowest solar cell mass of 84 mg/cm˛
. Third generation triple-junction (ZTJ) InGaP/InGaAs/Ge Solar Cells with n-on-p polarity on 140-µm Uniform Thickness Substrate
. Space-qualified with proven flight heritage
. Radiation resistance with P/Po = 0.90 @ 1-MeV, 5E14 e/cm˛ fluence
. Designed to accept corner-mounted silicon bypass diode for individual cell reverse bias protection
. Good mechanical strength for reduced attrition during assembly and laydown
. Standard and custom sizes available
Typical ZTJ illuminated I-V Plot
The period of performance for this program is about two years, said Emcore.
