Abstract

Embodiments of the present disclosure relate to a solar cell and a photovoltaic module. The solar cell includes a thin-film solar cell and a bottom cell stacked in a first direction. The bottom cell includes: a transparent conductive layer, a first doped conductive layer, an intrinsic amorphous silicon layer, a substrate, a second doped conductive layer, and one or more electrodes that are stacked in the first direction. The transparent conductive layer is between the thin-film solar cell and the first doped conductive layer, and the one or more electrodes are formed on a side of the second doped conductive layer away from the substrate and are in ohmic contact with the second doped conductive layer. The first doped conductive layer includes a doped amorphous silicon layer or a doped microcrystalline silicon layer. The solar cell is at least conducive to reduction of the collection loss of carriers of the solar cell and improvement of photoelectric conversion efficiency of the solar cell.
