Thermoelectric technology can be another direct way to convert solar radiation into electricity, using the Seebeck effect.
Herein, a prototype concentration solar thermoelectric generator (CTG) and a discrete numerical model for the evaluation of
the whole system are presented. The model takes into account the temperature dependence of the thermoelectric material properties
by dividing the thermoelectric leg into finite elements and is proved to be more accurate for calculation of the conversion
efficiency of the thermoelectric modules when large temperature gradients occur in the CTG system. Based on the best available
properties of various bulk thermoelectric materials reported in the literature, the best possible performance of the CTG system
is predicted, and the CTG system design, including the selection of the concentration ratio and the cooling method for different
thermoelectric materials, are discussed in detail. 相似文献

The Sn3.0Ag0.5Cu (wt.%) lead-free solder alloy is considered to be one of the most promising candidates to replace the traditionally used Sn–Pb solder. However, this alloy composition has some weaknesses, mainly as a result of its higher melting temperature compared to the eutectic Sn–Pb solder. In this paper, lead-free solder alloy nanoparticles of Sn3.0Ag0.5Cu were synthesized by chemical reduction with NaBH4 as reducing agent. The experimental results indicated that the major particle size of Sn3.0Ag0.5Cu nanoparticles was smaller than 100 nm. The melting and solidification properties of the Sn3.0Ag0.5Cu nanoparticles were studied by differential scanning calorimetry at different scanning rates. It was evidenced by the differential scanning calorimetry curves that the melting temperature of Sn3.0Ag0.5Cu nanoparticles was lower than that of the bulk alloy. In addition, the undercooling of the Sn3.0Ag0.5Cu nanoparticles was in the range of 82.0–88.5 °C at different cooling rates, which was much larger than that of the Sn3.0Ag0.5Cu micro-sized particles, showing stronger cooling rate dependence. 相似文献

The orientation-dependent out-of-plane dielectric properties of barium stannate titanate (Ba(Sn0.15Ti0.85)O3 (BTS)) thin films prepared by sol–gel method were investigated. Films with (1 0 0), (1 1 0), and (1 1 1) orientation were grown on LaNiO3-buffered (1 0 0), (1 1 0), and (1 1 1) LaAlO3 (LAO) single-crystal substrates, respectively. The different temperature of the dielectric constant maximum (Tm) of the BTS thin films with different orientation was believed to be attributing to stress inside the films. Films with the (1 1 1) orientation had higher relative dielectric constant and tunability than (1 0 0)- and (1 1 0)-oriented films. This difference in dielectric properties in these three kinds of oriented BTS films may be attributed to change in the direction and magnitude of electric polarization in orientation engineered BTS films and stress in the films. 相似文献
