SOLAR CELL MODULE, PHOTOVOLTAIC DEVICE, ELECTRIC APPARATUS, AND POWER GENERATION APPARATUS

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.
