The usage areas of GaSb cells in Turkey are quite limited and the studies are generally theoretical. In this study, the installation and analysis of the thermophotovoltaic system that provides electrical energy conversion from waste heat energy, considering international standards, has been emphasized. Experimental and theoretical data of thermophotovoltaic systems with high temperature GaSb cells were compared. Analysis was performed using five different cell temperatures with the OriginPro 2021 software and a new correlation was obtained for system analysis. As a result of the analysis, the efficiency value of the GaSb thermophotovoltaic cell systems was determined, and the radiation source temperature values were taken between 1000 K and 3000 K. Error analyzes were carried out by comparing the theoretical and real data obtained from the analysis. In the theoretical (lossless) analysis, the optimum energy conversion efficiency value of the GaSb solar cell structure was found to be 33.14%, while in the real (lossy) analysis it was 21.57%. This study presents a new method on energy conversion feasibility and improvement with major development project.
