Aiming to 15% of conversion efficiency /spl eta/ under the hot side T/sub h/=580/spl deg/C and the cold side T/sub c/=30/spl deg/C until March, 2007, 12% as midterm target was already well attained. In the next 2 years, module designing as well as materials tuning are surely the major topics in terms of superior durability. Bi-Te module, which is established as Peltier cooler, was adjusted to be suitable for generation purpose. So far, better than 7.8% of conversion efficiency with T/sub h/=280/spl deg/C and T/sub c/=30/spl deg/C was obtained and reproducibility was also well confirmed. Komatsu started investigation for suicide materials as well as module fabrication together with this NEDO project. The performance of suicide module using n-type Mg-Si and p-type MnSi are being steadily improved due to not only the elevation of Z-values of the materials but also maturity of module fabrication technique. Then, better than 8% of efficiency has been maintained at T/sub h/=550/spl deg/C and T/sub c/=30/spl deg/C. Besides each single module, the cascading one was successfully stacked and the performance was achieved almost as expected. /spl eta/=12.1% with T/sub h/=550/spl deg/C and T/sub c/=30/spl deg/C was actually accomplished up to now.","PeriodicalId":422400,"journal":{"name":"ICT 2005. 24th International Conference on Thermoelectrics, 2005.","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114954968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Quantities such as output power and efficiency, output voltage and current, inner resistance, and overall thermal conductance can be determined under vacuum or inert gas, but also in oxidising atmosphere. The heat flow through the generator is measured via the temperature gradient in a reference block at the hot side. The cold side heat flux is measured by a commercial heat flux meter, a second reference block or a combination of both. This redundant measurement provides a sensitive indicator for systematic errors caused by incomplete thermal shielding which would lead to thermal bypasses. Comparison of our generator tests a comparison with by a similar apparatus at another institution gives evidence for good measuring accuracy. The relative error of the resulting parameters is in the range of 5%. The method of heat flow detection in the GTF can also be used for thermal resistance investigations, especially on multi-layer systems of too low thermal conductivities for appropriate measurements by laser flash.","PeriodicalId":422400,"journal":{"name":"ICT 2005. 24th International Conference on Thermoelectrics, 2005.","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114190262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, the main assumptions used to derive the linear Boltzmann transport equations for electrons are examined and the possibility that a higher order transport coefficient may become relevant is discussed. In the linear transport regime, there is a fundamental trade off between high Seebeck coefficient and high electrical conductivity for bulk materials and for many multilayer structures due to the interplay between electronic density-of-states (DOS) and electron group velocity and also due to the shape of DOS versus energy curve deep inside a band. While low dimensional structures alter the density-of-states, a similar trade off still exists. If large barrier heights and high doping concentrations could be achieved solid-state thermionic energy converters would be able to alleviate this trade off, thereby achieving a very high thermoelectric power factor. For this to occur, the electron transverse momentum perpendicular to heterostructure barriers must not be conserved. This can be achieved with non-planar structures or with embedded nanostructures. Finally, a comparison between thermoelectric/thermionic devices and thermophotovoltaic energy converters shows a difference in the average energy of the emitted hot carriers due to the difference between electronic and photonic density-of-states in the reservoirs. The use of both electrons and photons from a hot reservoir or the engineering of the reservoir density-of-states may provide additional means to achieve higher efficiency in energy conversion devices and to approach the limit given by the entropy generation more easily.","PeriodicalId":422400,"journal":{"name":"ICT 2005. 24th International Conference on Thermoelectrics, 2005.","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129279784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
