A new configuration of a 1-10 W micro-thermophoto-voltaic (micro-TPV) device is studied experimentally and computationally. In the micro-TPV device thermal energy is directly converted into electrical energy through thermal radiation without any moving parts. For stable burning in a small confinement with uniform wall temperature, the present micro-emitter is a simple cylinder with an annular-type shield to apply for a heat-recirculation concept. The micro-emitter is surrounded with a chamber on the inner wall of which photovoltaic cells (PVCs) are supposed to be installed. The enhanced vacuumity of the PVC-installed chamber does not substantially affect the micro-TPV device performance, while the enhanced gap between the micro-emitter and PVC-installed chamber walls improves the cooling performance. For optimized design conditions, the results show that the present micro-TPV device configuration can be used in practical applications, avoiding frictional losses and clearance problems.
