Abstract

MicroLink Devices in collaboration with University of Notre Dame will develop composite lightweight, high-efficiency, epitaxial lift-off (ELO) inverted metamorphic (IMM) triple junction solar cells ideally suited for retrofitting current generation UAVs and integration with next generation platforms in order to substantially increase mission duration beyond current battery only technologies. MicroLink will target composite ELO solar cells (CSC) with ultra high specific power (>3.0 kW/kg) and very high areal power density (>370 W/m2). ELO is a unique disruptive technology that affords an attractive cost reduction model through substrate reclaim whereby the substrate after solar cell functional layers have been removed can be repolished and used for another solar cells growth. This model allows the cost of the substrate to be spread over several solar cell growth runs.
