A thermal-electrical-mechanical coupled model was established to simulate the Parallel-gap resistance welding (PGRW) process between the Germanium-based solar cell and the silver interconnector. The simulated results showed that the peak temperature during PGRW is lower than the melting temperature of the base material. It is indicated that the connection
Laser welding can be used to interconnect high-efficiency back-contact silicon solar cells with low-cost Al foil. This interconnection approach is relatively new and, thus,
In addition, employing perovskite/silicon solar cells aids in the maximum utilization of incident solar radiation due to bandgap differences between the different cells. PV technologies can also be used in agrivoltaic setups, where bifacial solar panels can be used to shade crops and also absorb irradiance from both panel faces. 2 Tandem Silicon/Perovskite
