Monitoring Hot Spots In Photovoltaic Systems

So far, solar energy is the most exploited alternative energy source, and photovoltaic technology is widely used for direct conversion of photons from the sun into electricity. However, the photovoltaic module efficiency decreases as the PV cell temperature increases. As a result, thermoelectric generators are coupled to the PV modules to improve its output power, efficiency and utilize the waste heat. Since a majority of the infrared region of the solar radiation is converted into waste heat, it increases the temperature...
