Several different kinds of materials, such as Pt, carbon and conducting polymer, have been used to fabricate counter electrodes in DSCs.
From this point, the applications of low-cost materials should be important.
In the future, large solar conversion systems producing electric power on the terawatt scale will prefer materials that are abundantly available.
It was found that the photovoltaic performance was strongly affected by the specific surface areas of the carbon materials [29].

Microstructure Evolution and Microhardness of 7075 Aluminum Alloy during Heat Treatment by Considering Hot Deformation History Sun Zhichao1,a, Yin Jilun1 and Yang He1 1 State Key Lab of Solidification Processing, Department of Materials Science and Engineering, Northwestern Polytechnical University, Xi’an, P.R.
Experimental material and method Fig. 1.
Original microstructure of as-extruded 7075 aluminum alloy The raw material of 7075 aluminum alloy was extruded bar (Φ80×1500mm) from Kunshan Huafeng aluminum industry Co., Ltd.
A higher deformation temperature can effectively reduce strain hardening degree and the dislocation density in the deforming material, further leads to a decline in stored energy.

Investigation on the absorption enhancement mechanism of aqueous LiBr using surface-active agent Yun Guo College of Mechanical Engineering, Shanghai University of Engineering Science Shanghai, People’s Republic of China graceguo1977@126.com Keywords: mechanism of enhancement; absorption; LiBr aqueous solution; active agent; heat and mass transfer Abstract.
Absorber, a key component affecting the LiBr absorption refrigerator performance, absorbs continuously low temperature vapor and pressure from the evaporator to ensure that the evaporator works all along at a lower pressure and that the refrigerator work stably，and its structure and performance determine the overall system size and efficiency.
To improve efficiency and reduce material, a host of countries have studied new high-efficiency absorbers, and in this regard they have produced some new findings.
