Inverted deformation multi-junction (IMM) solar technology developed by the U.S. Air Force Research Laboratory increases energy efficiency at a reduced cost and will be used primarily in military space applications.
The multi-layered light-absorbing material for each cell means that it can convert specific wavelengths of the solar spectrum into energy.
Allegedly, IMM battery than similar standard multi-junction solar cell array 15% higher power.
Developers said that the new solar cell can be used to solve the space community efficiency issues and public needs, and for other tools to release more satellite space.
"We found that by inverting the epitaxial cells on gallium arsenide we can more effectively tailor the material properties of each absorber layer," said Kerry Bennington, electronics engineer, AFRL Materials and Manufacturing.
