Within the sudden approximation, the photocurrent is proportional to the spectral function of a one-particle two-time retarded Green's function $\\mathcal{G}$ of an operator that creates an electron in a special quantum state $\\chi$ localized at the surface. For a system described by a many-body single-band model we present an analytical expression that relates the Green's function $\\mathcal{G}$ with the Green's function of an infinite crystal $G_{b,\\mathbf{k}}(\\omega)$ in Wannier representation.
