High-efficiency solar cells are demanded by all applications of photovoltaics, including terrestrial and space power generation, thermal energy conversion via thermophotovoltaics, and transmission via laser power conversion. Here, we demonstrate triple-junction III-V solar cells with higher efficiencies than previous record-efficiency six-junction devices. The devices incorporate high-performance thick GaInAs/GaAsP superlattices to enable an optimal bandgap combination. These cells are most useful for area-constrained terrestrial applications and low-radiation space missions, where efficiency is critical. As these are the highest efficiency one-sun solar cells as of this writing, these cells also set a new standard for achievable efficiency across all photovoltaic technologies.
