This paper reports the optimization of the molybdenum thin film electrode as the back contact of dye-sensitized solar cell (DSSC). The molybdenum thin film was grown on the glass substrate by direct current sputtering techniques of which the sputtering power was 150 W at 18 sccm flow rate of Ar. At such sputtering parameters, the Mo film can reach the lowest resistivity of 1.28E−6 cm at 400 nm thick. And the reflection of Mo membrane was 82%. This value is considered as a very good result for preparation of the back contact of DSSC.

The paper studies theories of material flow cost accounting (MFCA). The purpose of this paper is to analyse the reality in material management in Viet Nam thermal power plants (TPP). Research is based on the material flow theory, MFCA, the material balance for effective management of the production and material wastes during the manufacturing process. Costs in producing process based MFCA are included material cost, energy cost, system cost and waste management cost.

Currently, with the disappearance of fossil energy sources, finding new alternative energy sources is very necessary such as: solar energy, wind energy, tidal energy, flow energy, ... However, these energy sources require high investment capital, large capacity, and bulky size. In circuits requiring small power sources (below 12V), it is not applicable, or only used through intermediate devices such as transformers, current transformers; Therefore, the application of energy from mechanical vibration has been proposed as an optimal measure compared to the above methods..

One of the biggest inventions of human in the history is electricity. Coal, natural gas, uranium, tides, wind, and solar are resources for the generation of electricity. Hydropower first became the source of electricity back in the late nineteenth century. Water is the source of hydroelectric power which explains hydropower plants locations. Water volume and change in elevation from one to another point generate energy from the moving of water. More water flow and great elevation, more electricity (U.S. Energy Information Administration, 2020).
