In this study, the luminous flux was calculated by using the AM1.5G spectrum and imported into Matlab. Based on the Planck black body radiation formula and considering the photon chemical potential, the energy gap engineering of the triple-junction photovoltaic element was simulated and calculated by the detailed-balance calculation method for the best conversion efficiency of the energy band gap, there are Triple-junction (2-Terminal), Triple-junction (6-Terminal), Triple-junction hybrid/1T2B (4-Terminal), Triple-junction hybrid/2T1B (4-Terminal) four structures, and the materials suitable for 1T2B and 2T1B structures are further recommended; and the modularization of current matching and voltage matching is carried out for traditional triple-junction and hybrid 1T2B and 2T1B structures Design and optimize the number of batteries at the optimal energy bandgap point, and recommend a suitable module circuit design method after calculating the results. In the non-modular energy gap engineering, the 2-Terminal structure has a conversion efficiency of 51.12% when the top layer is 1.81 eV, the middle layer is 1.21 eV, and the bottom layer is 0.71 eV; in the 6-Terminal structure has a conversion efficiency of 51.95% when the top layer is 2.07 eV, the middle layer is 0.71 eV 1.41 eV, and the bottom layer is 0.93 eV; in the 1T2B structure has a conversion efficiency of 51.89% when the top layer is 2.13 eV, the bottom layer is 1.43 eV, and 0.93 eV; in the 2T1B structure has a conversion efficiency of 51.46% when top layer is 1.88 eV, and 1.34 eV, and the bottom layer is 0.71 eV. In the modular design, the traditional triple-junction structure, the voltage matching design method is better, and the number of batteries in the top, middle and bottom layers is 21, 34, and 60, and the conversion efficiency is 51.90%; in the 1T2B structure, the current matching design method is better. The number of batteries in the top and bottom layers is 36 and 60, and the conversion efficiency is 51.81%; in the 2T1B structure, the voltage matching design is better, and the number of batteries in the top and bottom layers is 10 and 60, which has a conversion efficiency of 51.47%. This result provides researchers with a reference for the research direction and modular design of triple-junction photovoltaic elements.
