Abstract

See full text

Disclosed are a double-sided solar cell and a preparation method therefor. The double-sided solar cell comprises: a silicon wafer having a PN junction, and a front first silicon oxide layer, a front second silicon oxide layer, a front first nitrogen-containing silicon compound layer, a front second nitrogen-containing silicon compound layer, and a front third silicon oxide layer that are located on one side of an N-type layer of the silicon wafer and are sequentially stacked along a direction away from the silicon wafer; and a passivation layer, a back silicon oxide layer, a back first nitrogen-containing silicon compound layer, and a back second nitrogen-containing silicon compound layer that are located on one side of a P-type layer of the silicon wafer and are sequentially stacked along the direction away from the silicon wafer.
