Light management in single and multi-junction solar cells is becoming increasingly important to optimize the optical and electro-optical properties of solar cells. The limits of light path enhancements are discussed for non-resonant and resonant optical nanostructures as well as for angular-selective and energy-selective approaches. The potential of 3D photonic crystals for photon management in solar cells is discussed for the corresponding concepts and the state of the art is reviewed.
