Open and hidden charm spectroscopy is an important tool to study QCD since they lie in the transition region between the short-range and long-range regimes of the strong interaction. This gives access to many non-perturbative effects as corrections to a perturbative approach. In the last decade the spectroscopy of hadrons especially in charm sector got a big push forward by the advent of new experimental possibilities like B-factories, where a number of new states (known as X,Y,Z and D_sJ) have been discovered. These could not easily be accommodated in simple potential models. Surprising as these discoveries were, neither statistical precision nor mass resolution are sufficient in order to fully characterize the new particles in terms of their masses, life times and quantum numbers. Progress in the quest to clarify the nature of these new particles can only be achieved by modern high statistics experiments with excellent mass resolution. The experiment PANDA, situated at the anti-proton storage ring HESR, both of which are planned at the new facility FAIR in Darmstadt, will focus on charm and charmonium spectroscopy. The unrivalled beam conditions of HESR together with the excellent coverage and capabilities of PANDA will offer the perfect environment to find yet undiscovered states and to precisely measure the properties of already known resonances.
