How portable solar panels work?

The photovoltaic cells in a portable solar panel contain various layers of silicon. When the rays of the sun hit the panel, photons are released which create an electric field between these layers of silicon in each cell. Metallic strips are attached to the panel to channelize this electric field and send it to the battery or grid on the basis of the system. A charge controller is connected to regulate the power output while a battery or grid on the basis of the system. A charge controller is connected to regulate the power output while a battery and inverter may also be connected to store the generated power until the time it is required.
