It reports on a novel device architecture which combines advantages from both lateral and vertical series interconnection, a new GaAs based champion device with a conversion efficiency of 68.9±2.8% under 858 nm monochromatic light, photonic power and data transmission, and PPCs for the O-band wavelengths around 1310 nm.enPhotovoltaikIII-V semiconductorphotonic powerPower-by-Lightpower-over-fiberIII-V- und Konzentrator-PhotovoltaikIII-V Epitaxie und Solarzellen621697conference paper
