Abstract
Provided are a solar cell, a method for preparing a photovoltaic module, and a photovoltaic module. The solar cell includes: a substrate, a first dielectric layer and a first doped conductive layer. The substrate has a first surface and a second surface opposite to the first surface. The first surface includes alternating electrode regions and non-electrode regions, and transition regions, each respective transition region of the transition regions being abutted on one side by a respective electrode region of the electrode regions and on an opposing side by a respective non-electrode region of the non-electrode regions. The transition region includes a plurality of spaced first pyramid structures and a plurality of micro-convex structures, and a one-dimensional size of a bottom of a respective micro-convex structure is smaller than a one-dimensional size of a bottom of a respective first pyramid structure.
