We investigated the migration of Sn and Pb onto the Ag fingers of crystalline Si solar cells in photovoltaic modules aged in field for 6 years. Layers of Sn and Pb were found on the Ag fingers down to the edge of the solar cells. This phenomenon is not observed in a standard acceleration test condition for PV modules. In contrast to the acceleration test conditions, field aging subjects the PV modules to solar irradiation and moisture condensation at the interface between the solar cells and the encapsulant. The solder ribbon releases Sn and Pb via repeated galvanic corrosion and the Sn and Pb precipitate on Ag fingers due to the light-induced plating under solar irradiation.

Сurrently Formula Student Motorsport competitions are actively gaining popularity in the world. These competitions are held exclusively for student teams whose goal is to develop, build and test racing cars. Competitions are divided into static and dynamic disciplines. The most important role among these disciplines is played by dynamic ones, which include such tests as: acceleration test, maneuverability, control accuracy, endurance race and energy efficiency. The main tasks of these tests are to pass various types of turns and difficult sections of the route.therefore, to get the best results, it is necessary to complete these tests in the shortest possible time. It is possible to achieve the desired result by achieving the best dynamic performance of the car. One of these problems solved in the design and manufacture of the Formula Student car is the problem of designing cross-stability stabilizers.
