  • Abstract
    InGaAs solar cells bonded to a Si substrate are demonstrated. These cells are 160 μm to 1300 μm in diameter and designed for integration in microsystems enabled photovoltaic systems. When compared to devices fabricated on substrate no degradation of cell performance was observed due to bonding. Additionally, the short circuit current for the cells correlated well with simulations indicating a low loss optical path through the bonding interface.
