  The brick wall model is a semi-classical approach to understanding the
microscopic origin of black hole entropy. We outline the formalism for the
brick wall model in arbitrary number of dimensions and generalize it to include
both charged spacetimes and charged probes in order to systematically show how
to calculate the entropy for any black hole, in higher orders of the WKB
approximation. We calculate the entropy for the Reissner-Nordstr\"{o}m and
charged BTZ black holes, and by looking at the chargeless limits we recover the
entropy of the Schwarzschild and neutral BTZ black holes. We also study
noncommutative corrections to the black hole entropy by using a Drinfeld twist
to deform spacetime symmetries. Using the noncommutative action for a charged
scalar field, we derive the noncommutative Klein-Gordon equation and the radial
equation in arbitrary dimension on which we generalize the brick wall method.
We study case by case the noncommutative Reissner-Nordstr\"{o}m and
noncommutative charged BTZ black holes, the entropy of which we calculate using
the generalized brick wall method. Corrections due to higher order in the WKB
approximation arise, and they are given by the logarithms of the black hole
area. The corrections in the lowest order of WKB due to noncommutativity are
also given by the logarithms of the black hole area.
