Preparation and Investigations of Some irradiated Thermoelectric materials

Abstract

Typically the energy costs were increased around the world and turned out to be one of the vital issues. Also, the growing energy demands convert into crises for many of the nations around the world. With all the accessibility of the enormous amount of the energy which comes from the sun (heat), there is a huge interest in harvesting this solar-powered energy[1-4]. For instance, A lot of countries were performed the extensive studies in solar power technology to enhance alternative sources of electric power generation. Because of the increase in the population as well as the demand for electricity is rising day in day out. With growing rate of population from the industrial counters, it is a desire to find other sources of energy to replace the conventional ones especially, when a large amount of energy is available during all the year from the sun energy.

On the other hand, many countries United States foe example, the electricity has been generated using Coal power plants since 1881, but today, they are using different sources of energy that are coal, hydroelectric, natural gas, nuclear and petroleum as well as a small amount from solar energy, wind generators and geothermal sources for electricity generation.

Figure (1.1) shows the electricity generation in Egypt in 2015/2016: Coal generation represented 32% of total power generation and solar generation accounted for 3% with wind which are renewable sources of
