We first introduce selected approaches, concepts and technological strategies to control light collection and absorption in photovoltaic ultrathin film cells for both solar and indoor light harvesting. We then illustrate light trapping into photonic crystal structures with examples of structures and devices, including 100nm thick hydrogenated amorphous silicon and 1µm thick crystalline layer solar cells. Finally, we discuss on the interest of photonic crystal structures to enhance non linear optical processes like down conversion for 3rd generation solar cells.
