Energy transfer occurs when energy is transferred from one object to another. In the case of solar panels, this energy transfer happens through a process called electromagnetic radiation.

Solar panels consist of photovoltaic cells that are made up of layers of semiconductor material. When sunlight strikes the cell’s surface, it excites the electrons in the material and causes them to move around rapidly. This movement of electrons creates an electrical current, which can be harnessed by a battery or used directly to power a house.
The energy transfer process begins at the top of the solar panel, where light enters through a transparent material called a filter. The filter removes any wavelengths of light that do not match the color spectrum of the sun. Next, the light travels down the cell face and into the layers of semiconductor material.
In the layer closest to the surface of the cell, there are chemical reactions taking place that create electricity. As the electrons move around the cell, they are influenced by other charges on the surface of the cell. This movement of electrons creates an electric field, which can be harnessed to generate electricity.
When sunlight reaches the bottom of the cell, it is reflected back up towards the top of the cell. This reflection of sunlight triggers a series of chemical reactions in the cell, which continue to generate electricity. As the electricity flows through the circuit, it is converted into usable voltage, which can be used to power homes or other electrical devices.

In summary, the process of energy transfer in solar panels involves the use of photovoltaic cells to capture sunlight and convert it into electricity. The energy transfer process begins at the top of the cell, where light enters through a transparent material. The light then travels down the cell face and into the layers of semiconductor material, where chemical reactions take place that generate electricity. Finally, the electricity flows through the circuit and is converted into usable voltage, which can be used to power homes or other electrical devices.
