摘要： A photovoltaic energy harvesting (PVEH) device comprises a single-junction photovoltaic cell. The photovoltaic cell includes a light converting element made of a wide band-gap III-V active material spectrally matched to an ambient light source, a light receiving side that is free from front metal contact gridlines, and at least one discrete metal contact element placed on the light receiving side that realizes power extraction. The active material of the light converting element may be made of (Al)GaInP compounds. The active material of the light converting element may be spectrally matched to ambient light in the form of at least one of an artificial light source and natural sunlight, and combinations thereof. The PVEH device may have a plurality of photovoltaic cells inter-connected in series to achieve a higher open-circuit voltage. A total fractional power loss due to series resistance, shunt resistance and contact shading is less than 20%.
