Energy-efficient hybrid solar collectors integrated into transparent building structures

The article addresses current issues related to the use of hybrid solar collectors that combine photovoltaic and thermal components for maximum utilization of solar radiation. The advantages of such systems in space-constrained conditions and their efficiency under various weather conditions are analyzed. The importance of creating stable and independent energy supply systems, unaffected by external factors, is emphasized, which is particularly relevant in the context of climate change and instability in the energy sector. The environmental benefits of hybrid solar collectors, which reduce CO₂ and other harmful emissions, are highlighted. The challenges associated with the design and implementation of such solar collectors, as well as the need to study their thermophysical characteristics, are outlined. The aim of the article is to conduct a detailed analysis of the development of solar thermal technology, verify existing solar collectors, and develop a method for calculating their ther-mal characteristics to improve efficiency.The article also explores various types of solar collectors and compiles their classification, including hybrid ones. A review of sources shows that hybrid solar collectors, which use liquid heat carriers to convert solar radiation into thermal energy, are available on the market. Currently, it is known that approximately 90% of solar radiation is absorbed by the surface of photovoltaic collectors, but only 15% is converted into electrical energy and 10% into thermal energy.A design of a hybrid solar collector with a heat exchanger, in which a liquid heat carrier circulates, and with vertical slats where photovoltaic elements are mounted, has been developed. These solutions allow such a solar collector to be inte-grated into the external envelope of a building.A model of the hybrid solar collector has been developed to study its thermal and electrical properties. The drawings show that photovoltaic elements can be applied to vertical shutters
