“…Another wavelength option is in the 1310 nm region, which also has interesting recent developments [30], and can benefit from the low fiber attenuation for that spectral region. Lastly, the long wavelength options of 1450-1490 nm and of the ~1550 nm region can both benefit from the lowest fiber attenuation range and from the telecommunication infrastructure [10,16,[35][36][37]39,42,44]. Much telecommunication traffic utilizes the ~1550 nm region; the ~1470 nm option can help minimize the potential for interference between optical wireless power transmission and data transmission applications.…”

The high-efficiency capabilities of multijunction laser power converters are demonstrated for high-power applications with an optical input of around 1470 nm. The InP-based photovoltaic power converting III-V semiconductor devices are designed here, with 10 lattice-matched subcells (PT10-InGaAs/InP), using thin InGaAs absorbing layers connected by transparent tunnel junctions. The results confirm that such long-wavelength power converter devices are capable of producing electrical output voltages greater than 4–5 V. The characteristics are compatible with common electronics requirements, and the optical input is well suited for propagation over long distances through fiber-based optical links. Conversion efficiencies of ~49% are measured at electrical outputs exceeding 7 W for an input wavelength of 1466 nm at 21 °C. The Power Converter Performance Chart has been updated with these PT10-InGaAs/InP results.

The photovoltaic converter (PVC) is a key device in a power-over-fiber system (PoFS). The aim of the work is to create a digital twin (DT) to predict the behaviour of PVC based on their specification data, which is the first step towards creating a universal DT of the entire PoFS. The paper considers the theoretical principles of operation of PVC using the zone theory of solids. A relationship has been established between the theoretical parameters and specification data of real converters. A five-element equivalent circuit of a PVC has been created and a DT in MATLAB Simulink has been developed on its basis. The dependences of the main parameters of the DT on the optical power at the converter input are calculated. Experiments were carried out on an installation with PVC of the YCH-H6424-15-FC-A brand. The optical powers at which all characteristics of the solar cell coincide with an accuracy of 2% are determined. The discrepancy between the calculated and experimental characteristics with increasing optical power is explained by the fact that the current transfer coefficient decreases at high current strength. This phenomenon is substantiated by the zone theory, but is not taken into account in the DT.
