Özet

This study presents the development and characterization of P3HT: Borophene-ZnO p-n junction-based organic thermoelectric generators (OTEGs), demonstrating superior performance compared to P3HT-ZnO systems. The incorporation of borophene significantly enhances electrical conductivity (reaching ~ 12 × 104 S/cm) while maintaining favorable Seebeck coefficients (~100–200 µV/K), particularly in the 400–500 K range, due to borophene's 2D conductive network that bridges the organic-inorganic interface. Structural analyses confirm the crystalline quality of borophene and its effective integration with P3HT. At the same time, thermoelectric tests show that the ternary composite achieves higher power factors than the binary P3HT-ZnO system, making it a promising candidate for mid-temperature waste heat recovery applications. The work advances organic thermoelectrics by optimizing the synergy between conductive 2D materials (borophene), polymers (P3HT), and metal oxides (ZnO) through innovative solution processing and junction engineering.
