A substrate, a solar cell, a photovoltaic system, and an electric device are provided. The substrate includes a first film layer, where at least one through-hole is provided on the first film layer. When the substrate undergoes bending, the first film layer bends and deforms accordingly. Since the through-hole is provided on the first film layer, the through-hole can reduce stress experienced by the first film layer surrounding the through-hole due to bending, thereby improving bending resistance of the first film layer, and further improving bending resistance of the substrate. This reduces a risk that the substrate develops bending marks, fractures, or breaks during repeated bending.
