“…HM-PVLPCs suffer from non-uniform illumination losses if each subcell does not receive the same light power density. [82][83][84] . This situation is likely to occur as a result of the tolerance in the HM-PVLPCs positioning in the encapsulation and packaging into optical fiber connectors.…”

“…A thorough experimental investigation on the impact of LPC misalignment is carried out in [77] for the evaluation of the passive assembly tolerance of the PV receiver with respect to the incident laser spot. In a subsequent work [78], the same authors developed a refined version of the experimental set-up previously used [77], together with a theoretical model to analyze tolerance requirements of existing MIM LPCs.…”

The high-efficiency conversion of photonic power into electrical power is of broad-range applicability to many industries due to its electrical isolation from the surrounding environment and immunity to electromagnetic interference which affects the performance and reliability of sensitive electronics. A photonic power converter, or phototransducer, can absorb several watts of infrared laser power transmitted through a multimode fiber and convert this to electrical power for remote use. To convert this power into a useful voltage, we have designed, simulated, and fabricated a photovoltaic phototransducer that generates >5 V using a monolithic, lattice-matched, vertically-stacked, single-cell device that eliminates complex fabrication and assembly steps. Experimental measurements have demonstrated a conversion efficiency of up to 60.1% under illumination of ~11 W/cm 2 at a wavelength of 835 nm, while simulations indicate that efficiencies reaching 70% should be realistically achievable using this novel design.Keywords: power over fiber, photovoltaic power converter, optical power transmission, photonic transducer, III-V semiconductor, remote power, electrical isolation, electromagnetic interference immunity.
