... the thermal stress under steady-state operation. However, residual stress analysis shows that the epoxy holding together the PV cell/aluminum nitride and aluminum nitride/heat sink pairs will likely break, first at some sporadic spots, and then in a good part of the bond causing the failure of the CPV module...

.... Both the modeling approaches predict heat sink temperatures within experimental uncertainty of a couple of degrees. Next, the 1-D axi-symmetric model is used to evaluate the sensitivity of different solar cell model assumptions, environmental effects (such as outdoor temperature, and the wind speed...

...Athanassios A. Argiriou; Spyridon P. Lykoudis; Constantinos A. Balaras; Demosthenes N. Asimakopoulos Coupling a building to the ground as a heat sink through earth-to-air heat exchangers can reduce the cooling energy demand during summer. The fans for circulating the air through the heat exchangers...
