  Fano and hybrid resonances of bilayer graphene could be attractive for
thermoelectric devices. The special profile presented by such resonances could
significantly enhance the Seebeck coefficient and the power factor. In this
work, we study the thermoelectric properties of bilayer graphene single and
double barrier structures. The charge carriers are described as massive chiral
particles through an effective Dirac-like Hamiltonian. The Hybrid matrix
method, the Landauer-B\"{u}ttiker formalism and the Cutler-Mott formula are
implemented to obtain the transmission, transport and thermoelectric
properties, respectively. The Seebeck coefficient and the power factor are
analyzed for gapless and gapped single and double barriers. We find that in the
energy range where Fano resonances occur, the Seebeck coefficient attains
values of tens of mV/K and the power factor reaches values of the order nW/K.
Hybrid resonances also sustain high values for the thermoelectric properties,
however not as high as Fano resonances. We also find that despite the Fano and
hybrid profiles are manifested in the conductance of gapped barrier structures,
the Seebeck coefficient and the power factor are systematically reduced as the
bandgap gets larger. So, our findings indicate that bilayer graphene barrier
structures can be used to improve the response of thermoelectric devices.
