Abstract. Infrared (IR) energy constitutes almost a half of the solar radiation coming to the Earth surface and almost 100% of the outgoing terrestrial radiation. Surprisingly, but such a huge energy flux is mostly considered as thermal waste and is not used for the practical needs on the large scale. Here, two major methods of the IR energy collection have been briefly reviewed, the direct one and harvesting through up-conversion to the visible range, where this energy can be picked up by the conventional solar cells. Advantages and disadvantages of the above methods have been discussed. Potential of application of IR dyes for IR energy collection has been demonstrated. Storage of the IR energy as a delayed way of its consumption has been also discussed.

Keywords: IR energy, thermodynamic balance, thermal converters, photoelectric converters, up-conversion, energy storage.
