Abstract

A solar cell, a manufacturing method, and a photovoltaic module are provided. In one aspect, an solar cell includes a silicon substrate, a first transport layer, and a carrier collection layer. The silicon substrate has a first surface and a second surface opposite to each other. The first transport layer is arranged on at least one of the first surface and the second surface. The first transport layer includes a polysilicon layer having an amorphous silicon region. The amorphous silicon region is arranged on at least a part of a surface of the polysilicon layer away from the silicon substrate. The carrier collection layer is arranged on the first transport layer, and at least a part of the carrier collection layer is in contact with the amorphous silicon region.
