The thermal Sunyaev-Zeldovich effect is the spectral distortion of the Cosmic Background Radiation produced by the inverse Compton scattering on hot electrons in clusters of galaxies. After a short description of the effect and its utility as cosmological probe, we review the recent theoretical calculations, and in particular our method for arbitrary optical depth and electron temperature, by solving numerically the exact Boltzmann equation for the photon distribution function.
