The opposing charges between these two layers, through the exchange of electrons from the n-layer to the p-layer, form a microscopic electric field at their interface. Each solar cell is made with a positively-charged silicon layer (p-type) sandwiched beneath a negatively charged silicon layer (n-type). Solar cells are made up of silicon, which is a type of semiconductor material (a material that can act as either an insulator or as a conductor). Solar cells are tiny electrical devices that convert energy from a light source, such as the sun, into electricity. Solar panels are made up of solar cells, also called photovoltaic cells. On your solar circuit diagram, use arrows to illustrate the flow of electrons, and write a brief explanation of how electricity is generated and flows through the circuit.The typical components of an average solar garden light Your sketch should look something like this, but may have different components or connections: Use the checklist of electrical components and symbols to represent each of the items you see inside the circuit. In your engineering notebook, draw the circuit you discovered inside the solar device showing the connection between the different components.Sketch And Explain The Solar Circuit That You Explored Use the checklist in your engineering notebook to guide you as you discover each of the components in the circuit. Here’s what you might find: a solar panel, LED bulb, transistor, battery holder with a battery, transistor and a chip. Carefully examine the inside of the device and all of the individual circuit components. Avoid puncturing any of the electrical components some may need force to be applied before they can be removed. With the help of an adult, use tools like a screwdriver to remove all inner circuit components, being careful not to break individual components as you work.Get an adult to help break apart one or more of the outer coverings of a solar-powered device.Ensure that all observers and participants are wearing safety glasses and work gloves to protect your eyes and hands during the activity from plastic fragments.Safety glasses and leather work gloves (for all observers).Precision screwdriver set, hammer, flathead screwdriver.mini spotlights, stake lights, pathway lights, or a solar-powered dancing toy) Teacher Note: If you’d like your students to still be able to see the disassembly process you can do it as a demonstration in groups with students, or provide them with the light after you have taken it apart. This activity requires appropriate safety equipment for all observers and participants and should be closely supervised by an adult.
