What is the basic principle of PV?
The photovoltaic effect is the physical process of converting light into electricity. The photovoltaic principle has the following minimal requirements: A two-level system, where there is at least one type of carrier that can make a transition from the lower (relaxed) to the upper (excited) state.
What is the working principle of solar cell briefly answer this?
Silicon crystals are laminated into n-type and p-type layers, stacked on top of each other. Light striking the crystals induces the “photovoltaic effect,” which generates electricity. The electricity produced is called direct current (DC) and can be used immediately or stored in a battery.
How is a solar cell made explain its working?
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 is a solar cell made explain its working class 12?
Construction of a solar cell – usually a somewhat thick layer of n-type semiconductor is layered by a thin layer of p-type semiconductor. … Working principle, when light strikes the surface of the cell, it penetrates to the pn junction created by the fusion p-type semiconductor and the n-type semiconductor.
What is solar cell class6?
Answer: A cell which directly converts the light coming from the sun into electrical energy is known as a solar cell.
