Development and characterization of sandwich hybrid photovoltaic-thermoelectric generator using shingle as a thermal buffer for efficiency improvement

Photovoltaic (PV) systems suffer from significant thermal energy loss, inextricably linked to the photo-electric conversion process due to the high PV operating temperature above the 25 oC standard test conditions (STC). The direct contact of TEG with PV in the PV-TEG hybrid system also increases th...

description Photovoltaic (PV) systems suffer from significant thermal energy loss, inextricably linked to the photo-electric conversion process due to the high PV operating temperature above the 25 oC standard test conditions (STC). The direct contact of TEG with PV in the PV-TEG hybrid system also increases the temperature, this always decreases about 30 % in the system output power and about 0.1-0.5% efficiency drop for every 1 oC rise above STC. A Hybrid Photovoltaic-Thermoelectric Generators (PV-TEG) are system that can generate both electricity and heat. The TEG in the hybrid system provides a solution to significant temperature increases by cooling the PV cells and therefore increasing electrical power output. An integrated hybrid system where the PV modules are placed on the top of a shingle while the TEGs were attached to the attic side of the shingle for improved performance is proposed and investigated in this study. The objectives of the study are therefore to simulate the system using ANSYS and MATLAB Software, develop a hybrid PV-TEG system called sandwich shingle configuration for a housing roof experimentally so as to analyse the effect of the operating temperature, output voltage, and output current on TEG alone and PV alone on the system performance and to investigate the hybrid PV-TEG system power and efficiency using a single layer positioned between the PV and TEG through real-time experiment.
