Holger Kleinke's research focuses on finding and optimizing new thermoelectric materials.  Thermoelectrics are capable of converting heat into electrical energy and vice versa.  This environmentally friendly energy conversion currently has several applications, but is limited by its low efficiency.  His research group is attempting to increase the efficiency so that thermoelectrics may be used to recover electricity from the nowadays abundant waste heat, e.g. in the exhaust of automobiles.
