Abstract

See full text

Provided is a tandem photovoltaic device comprising: a top cell, a bottom cell, and a first light-trapping structure, in stacking, wherein a band-gap width of the top cell is larger than that of the bottom cell; and at least one of a second light-trapping structure located on a side of a shading surface of the bottom cell and a third light-trapping structure located on a side of a phototropic surface of the top cell; the three light-trapping structures are selected from metal or semiconductor material, and localized surface plasmons generated by the three light-trapping structures correspond to different peaks of light-wave response; and the three light-trapping structures form microstructures on a first cross section, average sizes d1, d2 and d3 of projections of the microstructures and average distances w1, w2 and w3 between the microstructures have relationships:
