We show that after annealing at 250/spl deg/C under He atmosphere, the figure of merit of the layers increases to Z=3.2/spl times/10/sup -3/ K/sup -1/ for /spl alpha/=240 /spl mu/V/K and /spl rho/=12 /spl mu//spl Omega/.m for p type material and Z=1.6x10/sup -3/ K/sup -1/ for /spl alpha/=200 /spl mu/V/K and /spl rho/=15 /spl mu//spl Omega/.m for n type material (at 300 K). With these fabrication parameters we realised three different structures of micro-module Peltier (MMP) junctions and we obtained a maximum value for temperature drop between hot and cold sides of about 3.4 K. This result is very promising in order to develop micro-module Peltier (MMP) effects.","PeriodicalId":174813,"journal":{"name":"XVI ICT '97.

Tungsten or carbon electrodes were joined to either side of n-type Si/sub 0.8/Ge/sub 0.2/ (P 0.3 at.%) respectively, with thin sheets of titanium foil inserted between them, and then pressed and joined at 1523 K in vacuum. The size of the resulting electrode/SiGe semiconductor/electrode units measured 5 mm/spl times/ 5 mm/spl times/9 mm. Observations through SEM and EPMA showed the presence of many voids in the junction layers of the SiGe/tungsten electrodes, whereas the SiGe/carbon electrodes exhibited no voids in their junction layers. In the SiGe/carbon electrodes, the titanium atoms were enriched in the junction layer, and other atoms also remained undiffused. In the SiGe/tungsten electrodes, the tungsten and silicon atoms showed counter diffusion. Resistance and Seebeck coefficient of the carbon/SiGe/carbon electrodes were measured in the temperature range from 600 to 1100 K. Resistance ranged from 0.012 to 0.015 /spl Omega/, and the Seebeck coefficient from 200/spl times/10/sup -6/ to 250/spl times/10/sup -6/ V/K. To evaluate the upper limit of heating dependence, the carbon/SiGe/carbon electrodes were exposed in an argon atmosphere at 1273 K and 1373 K for 300 hours. After exposure testing, SEM observation showed the presence of many voids in the junction layer of the SiGe/carbon electrode, which had not previously shown any voids either at the stage of joining by hot-pressing or exposure at 1273 K.","PeriodicalId":174813,"journal":{"name":"XVI ICT '97.

A modified thermoelectric generator from the Canadian Global Thermoelectric company has been used as the auxiliary generator. A microprocessor-controlled energy management system (EMS) allows fully automatic operation with minimal use of fossil fuels and appropriate battery operation management. As the auxiliary power supply can support the PV generator in supplying power to the load during periods with little sunlight, a very reliable power supply is achieved. Further, the dimensions of the PV generator and the battery capacity can be reduced without affecting the supply reliability. In Central Europe, for instance, the size of the PV generator can be reduced to a third of that needed for an exclusively PV system, if only 10% of the annual demand is met by the auxiliary generator. This allows a compact construction of the photovoltaic hybrid system and helps the numerous requirements on isolated telecommunications facilities to be fulfilled.","PeriodicalId":174813,"journal":{"name":"XVI ICT '97.
