Abstract
New microdevices have attracted much attention due to their small size and high efficiency in energy conversion.Thermoelectric generators,thermal photovoltaic cells,thermionic devices and thermal radiation batteries constitute a new type of micro-devices,which provide an effective way to promote the development of new energy sources and effectively recover waste heat.These solid-state energy conversion devices operate between two heat sources at different temperatures,and convert the heat part into electrical energy efficiently by physical mechanism,showing excellent power density and conversion efficiency.The study explores the thermodynamic characteristics of new energy conversion microdevices.The results show that these new micro-devices perform well in energy conversion efficiency,which can satisfy the urgent need for clean and efficient energy,so as to provide support for the development of energy conversion technologies.
