Light management in single and tandem solar cells is becoming increasingly important to optimize the optical and electro-optical properties of solar cells. After a short introduction to state-of-the-art light management approaches, different applications of photonic crystals for photon management in solar cells are reviewed and discussed concerning their applicability. Results on direction- and energy-selective filters for ultra-lighttrapping, intermediate reflectors for optimal current matching in tandem cells, and photonic crystal coating for fluorescence collectors will be presented and discussed.
