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.

study, statistical data, periods of incapacity and number of fatal cases related to occupational accidents between the years 2012-2020 were obtained from the Social Security Institution (SSI). By analyzing the data, occupational accident severity rates and occupational accident frequency rates for years were determined and compared without making any sectoral discrimination. In particular, the curfew in the conditions of the Covid-19 pandemic, working
from home, stopping certain sector works, etc. The rate of active workers in business life, which occurred after the implementation of the measures, decreased rapidly. In order to protect the worker, a dismissal ban was introduced, resulting in unrealistic results in the occupational
accident severity rate calculations due to the fact that the worker did not go to the workplace or worked from home despite being actively registered as an active worker in the SSI system. It can be suggested that the state should not leave occupational health and safety only as a documentation on the law, and that it can prevent occupational accidents by creating an occupational health and safety culture in Turkey by cooperating with employers and workers.
