Today, one of the factors to optimize and increase the efficiency of photovoltaic systems is to move to the hybrid path and increase their efficiency. In this regard, much research has been done in the field of thermal photovoltaic systems (PVT) and centralized photovoltaic thermal systems (CPVT). Major work on CPVT systems and their cooling on a laboratory scale is still in the Research phase. The paper discusses work related to the design, modeling, prototype testing, various cooling technologies, and CPVT sunlight focus, and focuses on its various components, such as concentrators, cooling converters, and sunlight receiver geometries. And coolant work. In this dissertation, a simultaneous hybrid concentrated thermal photovoltaic system (PVT / CPVT) was designed and built on a linear parabolic concentrator, which was experimentally investigated for heat generation and combined power. In designing the geometry of the sunlight receiver and photovoltaic modules, it was designed in the shape of a triangle that can absorb light from three sides and can act as two CPVT receivers and one PVT receiver at the same time. To evaluate the performance of the built system, another receiver with common rectangular geometry was considered, the results of each of which were comparable. To cool photovoltaic modules from micro-channel converters, which are one of the most efficient types of heat exchangers, were designed and assembled in the form of a triangle with the highest angle of absorption of sunlight. After building the final system, several different scenarios were considered for operational tests. During the test, the flow rates varied from 3, 5, 7, and 9 kg / h. The results of field experiments showed that the average thermal and electrical efficiencies of CPVT and PVT systems were 60, 13%, 34%, and 13.3%, respectively.
