The present invention relates to the technical field of solar cells, and more particularly to a device structure and manufacturing method for an N-type silicon PERT bifacial solar cell. The device structure comprises a front electrode, a front-side anti-reflection layer, a passivation layer, a p+ emitter, an N-type monocrystalline silicon wafer, an n+ back surface field, a rear-side anti-reflection layer, and a rear electrode. The n+ back surface field is a composite thin-film structure consisting of an amorphous silicon layer, a microcrystalline silicon layer, and a polycrystalline silicon layer. The design replaces the conventional thermally diffused back field with doped microcrystalline and polycrystalline silicon thin films, effectively avoiding bulk defects in the silicon wafer such as dislocations and lattice distortion caused by phosphorus impurities. This structure forms a graded back surface field and a refractive-index-graded optical composite film, thereby achieving dual optimization of electrical and optical performance. As a result, the open-circuit voltage and short-circuit current are improved, which leads to an increase in the overall conversion efficiency of the solar cell.
