R&D on nitride-based heterogeneous tandem solar cells on Si substrates

Research Project Outline

We target realization of heterogeneous tandem solar cells made of group-III nitrides and Si, which are assumed to be highly familiar with concentrator photovoltaic systems and likely to be promising for bringing about low-cost, high-efficient, and low-environment-load solar cells. We explore technologies for growing group-III nitrides with bandgap energies corresponding to visible and infrared lights on Si substrates and technologies for designing, fabricating, and hybridizing solar cells composed of nitrides. We also advance researches related to growth, characterization, and device fabrication of In-rich nitrides.
