Lattice-Mismatched Approaches for High-Performance, III-V Photovoltaic Energy Converters

    Research output: Contribution to conferencePaper

    Abstract

    We discuss lattice-mismatched (LMM) approaches using compositionally step-graded layers and buffer layers that yield III-V photovoltaic devices with performance parameters equaling those of similar lattice-matched (LM) devices. Our progress in developing high-performance, LMM, InP-based GaInAs/InAsP materials and devices for thermophotovoltaic (TPV) energy conversion is highlighted. A novel,monolithic, multi-bandgap, tandem device for solar PV (SPV) conversion involving LMM materials is also presented, along with promising preliminary performance results.
