Experimental Investigation of PVT System Combined with Thermoelectric Module
, M.Sc. Thesis Sharif University of Technology ; shafii, Behshad (Supervisor) ; Saboohi, Yadollah (Supervisor)
Abstract
Photovoltaic phenomena is the base of Photovoltaic cells technology that can transform the solar insolation to electricity directly. In this transformation, the solar insolation intensity is the important factor to increase the performance of the Photovoltaic cells but one of the biggest barriers in the extension way of this technology is its more cost that need to be decrease. Concentration of solar radiation method is the best way to increase the performance of Photovoltaic systems and decrease its initial cost. At this project a novel structure of solar parabolic through concentrator is investigated experimentally and analytically. The usage of Thermoelectric module with Photovoltaic...
Experimental Investigation of Photovoltaic/thermal-Thermoelectric Hybrid System with Phase Change Material
, M.Sc. Thesis Sharif University of Technology ; Shafiee, Mohammad Behshad (Supervisor) ; Borooshaki, Mehrdad (Supervisor)
Abstract
Nowadays energy consumption increases in our daily life and incredibly enhancement of growth rate can be seen recent years. Hence, the use of renewable energy is prioritized. Solar energy is one of the choices because it is free and available. In this research, it has been tried to get electrical and thermal power at a reasonable cost both during the day and night. The system is equipped with a linear parabolic concentrator with a collector installed in the center of the concentrator which has been installed on its faces photovoltaic cells and thermoelectric modules, and five different systems have been tested with different components. Also, the paraffin has been used as a phase change...
Optimal Design of Energy Supply Units Using Solar Energy

Abstract
The sun, as the world's largest source of energy, had always affected various aspects of human life. Several studies on the use of solar energy in various forms have been reported. Parabolic trough solar collectors are one of the most common ways to use solar thermal energy. Many investigations have been carried out on the study of various parameters of this system and their effect on the efficiency. In this study, a detailed numerical study on the impact of thermo-physical properties of the heat transfer fluid on the system efficiency have been performed and the fluid have been optimized. Parabolic trough solar collector is modelled by dividing the structure of the device into three layers:...

Abstract
The solar collectors have been commonly used in desalination systems. Recent investigations show that the use of a linear parabolic through collector in solar stills can improve the efficiency of a desalination system. In this work, a combination of a heat pipe and a twin-glass evacuated tube collector is utilized with a parabolic through collector. Results show that the rate of production and efficiency can reach to 0.27 kg/(m2 h) and 22.1% when aluminum conducting foils are used in the space between the heat pipe and the twin-glass evacuated tube collector to transfer heat from the tube collector to the heat pipe. When oil is used as a medium for the transfer of heat, filling the space...
Manufacture and Experimental Study of the Desalination System and Atmospheric Water Generator with Evacuated Tube Collector
, M.Sc. Thesis Sharif University of Technology ; Shafii, Mohammad Behshad (Supervisor)
Abstract
This research aims to design and build a device that Using solar energy and can be used as water heaters and water desalination and water from the soluble hygroscopic. For this purpose, a combination of evacuated tube collector with parabolic through collector with sun tracking mechanism is used. sun tracking mechanism is polar and works with optical sensor. in this research we have designed new setup with evacuated tube collector for direct desalination and water heater. in this method heat pipes have been omitted from setup that cause high performance in heat transfer from evacuated tube collector to water and is minimized losses. 15w air compressor used to increased rate of evaporation ...
