In this paper, we discuss some of the highlights of the Fifth Conference on Thermophotovoltaic Generation of Electricity. The paper is organized into three principal sections, which deal with systems, infrared radiation emitters, and photovoltaic cells. Significant areas of progress and trends are identified in each of these areas. Progress is occurring at the fundamental level of materials' science, radiation physics, and systems. In the third of these topics, the quaternary alloy GaInAsSb appears to have become increasingly favoured. In the second topic, interesting developments in surface structured radiators and close-proximity radiators is discussed. Finally, we note that increased work on systems is still required, particularly for non-military applications.
