title: Basic limit for the efficiency of coherence-limited solar power conversion.
abstract: A basic upper bound for the efficiency of solar power conversion (generally, from any blackbody source) is derived, generalizing the Landsberg limit to arbitrary solar and sky view factors (e.g., arbitrary concentration or angular confinement), and to coherence-limited devices such as rectifying aperture antennas.
