Thermoelectric Power Generation By Using Solar Parabolic Trough Reflector
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 11
Abstract
In the present rapidly developing world, generation and consumption of electrical energy playing an important role without harming the nature of the environment. To achieve the environment-friendly electrical power generation a lot of research was done and succeeded with technologies such as photovoltaic, concentrated solar power, wind energy, tidal energy...etc. This work is attempting a new way to convert solar energy into electrical energy by using a series of Thermocouples and parabolic trough reflector. Series of Thermocouples contain a number of hot and cold Junctions. Thermocouple hot junctions were arranged at the focal point of parabolic trough reflector whereas cold junctions insulated with some thermal insulation to reduce heat transfer. Parabolic trough reflector concentrates solar radiation at thermocouple hot junctions; this increases intensity of radiation due to this temperature of hot junction increases. Cold junctions are maintained at low temperature by using an external cooling medium. The temperature difference between hot and cold junction induces an e.m.f in series of thermocouples. Voltage and current generated during the experiment is measured by using a multimeter. In this work, results were taken for different Thermocouple materials with the different parabolic reflective surface combinations. Some suggestions are also made for improving the system performance.
