Summary: Photon enhanced thermionic emission (PETE) is a solar power technology that converts photons into energy via photovoltaic and thermionic emission. This paper proposes an isothermal thermoradiative enhanced-PETE (iTR-PETE) configuration and develops a thermodynamic model to evaluate the factors affecting solar conversion efficiency. The study shows that the iTR-PETE combined system has a significantly higher conversion efficiency compared to the conventional PETE combined system.

Summary: The main purpose of this study is to create and validate a model that approximates the temperature trend of a receiver installed in a concentrated solar plant. Two models were developed using the Monte Carlo method for ray tracing, with one setting the maximum reflectivity of the paraboloid and the other setting a reflectivity of 80%. The optical and thermal performance of the receiver were calculated and compared to the manufacturer's values, and the model was validated by comparing the obtained temperatures with those measured by thermocouples. The average error was found to be 7% and 2% for two random days in 2020.
