Focussing on spectroscopic aspects of semiconductors and insulators we will illustrate how quasiparticle energy calculations in the G(0)W(0) approximation can be successfully combined with density-functional theory calculations in the exact-exchange optimised effective potential approach (OEPx) to achieve a first principles description of the electronic structure that overcomes the limitations of local- or gradient-corrected DFT functionals (LDA and GGA).
