Dark matter particles from the galactic halo could interact with solar nuclei and be captured by the Sun either in external orbits or in its
core. In both scenarios, a gamma-ray signal from the Sun is expected, with photons originating directly from annihilating pairs of dark-matter particles or
from their annihilation into long-lived intermediate states which in turn decay into photons. In this contribution we will present the results of a dedicated
analysis using a 10-years sample of photons collected by the Fermi LAT, searching for dark matter signatures in the gamma-ray energy spectrum towards the Sun.
