Crystalline silicon is a stable material. 9 thg 2, 2018
How do electrons move in solar panel?
When sunlight strikes a solar cell, electrons in the silicon are ejected, which results in the formation of “holes”—the vacancies left behind by the escaping electrons. If this happens in the electric field, the field will move electrons to the n-type layer and holes to the p-type layer.
How does pn junction work in solar cell?
Voltage is generated in a solar cell by a process known as the “”photovoltaic effect””. The collection of light-generated carriers by the p-n junction causes a movement of electrons to the n-type side and holes to the p-type side of the junction.
