While stacked hybrid systems integrating perovskite solar cells (PSCs) and thermoelectric generators (TEGs) enhance solar spectrum utilization, achieving complete utilization remains a challenge. To tackle this issue, a novel spectral beam splitting photovoltaic–thermoelectric hybrid system (SBSPHS), which encompassed a spectral beam splitter, PSC, TEG, solar concentrator, and solar collector, was reported. A mathematical model for the SBSPHS was developed by accounting for various physical and chemical processes, through which the performance features and influential laws were unveiled. After model validation, the SBSPHS preliminarily reported a maximum conversion efficiency of 23.16%, which was 1.18 times greater than that of independent PSC (19.67%), showing bright prospects. A series of parametric analyses identified several optimizable factors, including the operating temperature of PSC, the operating temperature of the solar collector, lengths of TEG semiconductor legs, cross‐sectional areas of TEG semiconductor legs, TEG's structural parameters, doping concentration of absorber layer, thickness of absorption layer, interface defect densities, and cut‐off wavelength. The detailed explanations of these factors’ influential mechanisms were provided. These findings provide quantitative insights into the performance potential and key mechanisms of an SBSPHS.
