The study of the peculiarities of operational parameters and the establishment of optimal operating modes of a hybrid collector with the ability to generate electric current and heat. Development of the technology for synthesizing bio-carbon materials for high-capacity supercapacitors and study of their performance characteristics. Optimal balancing of the combined battery by connecting the supercapacitor to the battery. popup.description2 Within the reporting period, technologies have been developed for the formation of hierarchical clathrate structures based on layered GaSe and InSe crystals as well as mesoporous SiO₂ matrices (MCM-41, SBA-15). Their electrophysical properties have been characterized, including magneto- and photoresistive effects, pseudocapacitive charge storage mechanisms, manifestations of quantum-size effects, and memristive behavior. A generalized model of quasi-2D crystals has been proposed to describe electronic states and the influence of external fields. Supercapacitor cells were optimized through femtosecond laser modification of aluminum current collectors with the formation of LIPSS, which resulted in reduced internal resistance and increased specific capacitance. Comparative pulse-mode testing (200 J) of battery, supercapacitor, and hybrid power sources was performed. The hybrid system demonstrated the best power characteristics and operational stability. Experimental and numerical studies of a hybrid solar collector with a thermal energy storage system were carried out. Optimal operating conditions were determined (heat transfer fluid flow rate of 0.02 kg/(s·m²), solar irradiance of 900 W/m²), achieving a thermal efficiency of 0.82–0.85 and instantaneous thermal power up to 511 W/m². The obtained results confirm the scientific validity and technical prospects of developing an integrated hybrid solar energy supply system with enhanced efficiency and functional stability.
