Thermoelectric (TE) materials directly convert thermal energy into electrical energy, offering a promising solid-state solution for clean energy application. TE generators needs less area and less expensive in construction and which can be operated in various kinds of environmental conditions. Therefore, TE generator could be much more attractive for waste heat regeneration. For thermoelectric devices to make a significant impact on energy and environment, the major impediment is the efficiency and the cost of current thermoelectric materials. In this talk, I focus on inexpensive doped TE materials and TE power generator modules. On the other hand, thermoelectric generators (TEG) have long been relegated to use in space-based or other niche applications, but are now being actively considered for solid state cooling systems. We construct a solid state air conditioner consisting of TEGs to extract heat from the lift with the use of the electricity. No noise and water are produced during the cooling process; therefore, such an instrument is extremely promising for thermoelectric (i.e. TE) cooling application because it has outstanding cooling capacity and rapid cooling process as well as long working life. In addition, the refrigeration and air conditioning technology based on thermo-electricity is “green” initiatives due to the absence of a harmful chemical refrigerant.
