Resumen de: AU2025382877A1
The present application relates to a solar cell module, a photovoltaic device, an electric apparatus, and a power generation apparatus. In the solar cell module, two busbars are used to respectively connect a junction box to a positive electrode end and a negative electrode end of a cell body, so as to realize the electrical connection between the junction box and the cell body. During structural design of the busbars, at least one busbar can be designed to comprise a first busbar portion, an extending portion, and a connecting portion, wherein the extending portion is located outside of one end of the cell body in a second direction. It can be seen therefrom that when electrically connected to the junction box, the extending portion is led outside of one end of the cell body, such that the distribution of the portion of the busbar located between the positive electrode end or the negative electrode end and the junction box on the surface of the cell body is reduced, thus reducing the probability of stress concentration caused by the busbar to the cell body, and improving the stability of the solar cell module.

Each housing eccentrically contains the rotating shaft from the housing's geometric center. The radial arm length of each VAETMA continuously changes with respect to rotation angle. When the turbine rotates by gravity, the VAETMAs induce the inertial centrifugal force differences toward the longest arm direction and the twisting moment differences in both half planes creating resultant twisting moment (torsion) on the rotating shaft. The resultant twisting moment drives several of the driving wheels which simultaneously and frictionally rotate the set of 3-φ electric power generators. Four levels of AI control the optimal performance of a distributed electric power network.
