Photovoltaic–Thermoelectrical Generator Using Concentrated Solar Energy

Electrical energy can be generated by using solar energy concentration. Normally, this type of systems requires a special device to achieve optimal heat dissipation. A no cover power Bi-Junction Transistor (BJT) has this advantage. An electrical power generator may be obtained if concentrated solar radiation is applied directly to the surface of a power transistor such as the MJ15023. The waste heat of the BJT is removed by a power thermoelectric module, and then a co-generation system may be obtained. This paper shows how this system is implemented and the results are evaluated to show the advantages of this type of generator.
