Abstract The radial parts of the gravitational, electromagnetic, neutrino, and massless scalar fields in Barriola-Vilenkin spacetime are transformed to the form of the Teukolsky-type master equation. The first quantum corrections to the entropy of the black hole due to the spin fields are calculated by using the brick wall model. It is shown that the contribution of any one of the spin fields is quadratically divergent at the event horizon and is proportional to the surface area of the event horizon.
