When sunlight hits the semiconductor material in a photovoltaic cell, it excites electrons, allowing them to move and create an electric current. The semiconductor layers in the cell are designed to facilitate this movement of electrons through the circuit, generating electricity. This process is known as the photovoltaic effect and is what enables solar cells to convert sunlight into usable electrical energy.

Which tool converts sunlight into electricity?
A solar panel converts sunlight into electricity through the photovoltaic effect. When light hits the solar cells, it generates an electric current by freeing electrons in the material. These electrons can then flow as electricity to power various devices.
How does the photovoltaic cell work?
Photovoltaic energy is the conversion of sunlight into electricity. A photovoltaic cell, commonly called a solar cell or PV, is the technology used to convert solar energy directly into electrical power. A photovoltaic cell is a nonmechanical device usually made from silicon alloys. When light strikes these silicon alloys, it frees electrons which can be collected onto attached conductive plates.
What does a photovoltaic cell do?
A photovoltaic cell converts sunlight into electricity through the photovoltaic effect, where photons from the sunlight knock loose electrons in the cell's material, creating an electric current. This electricity can be used to power homes, businesses, or devices.
How is electricity transmitted through a conducting wire?
Electricity is transmitted through a conducting wire by the movement of electrons. When a voltage is applied to the wire, it creates an electric field that pushes the electrons along the wire, allowing the flow of electricity from one point to another.
How does the Photovoltaic effect work?
The photovoltaic effect is the process by which sunlight is converted into electricity in solar cells. When sunlight photons strike the solar cell, they knock electrons free from the atoms in the material, creating an electric current. This flow of electrons generates electricity that can be used to power electronic devices or be stored in batteries.

How is energy harvested from solar photovoltaic?
Solar photovoltaic cells convert sunlight into electricity through the photovoltaic effect. When sunlight strikes the cells, electrons are knocked loose from the atoms in the cell, creating an electric current. This direct current (DC) electricity is then converted into alternating current (AC) electricity using an inverter for use in homes or businesses.
How does energy from the sun generate electricity?
Solar panels contain photovoltaic cells that convert sunlight into electricity through the photovoltaic effect. When sunlight hits the solar panels, it excites electrons in the cells, which generates an electric current. This current is then collected and converted into usable electricity for homes or businesses.
Is conducting electricity a physical or chemical property?
Conducting electricity is a physical property of a material, as it involves the movement of electrons within the material in response to an electric field. A material's ability to conduct electricity is determined by its atomic structure and how freely electrons can move within it.
How do photovoltaic systems work to convert sunlight into electricity?
Photovoltaic systems work by using solar panels made of silicon cells to capture sunlight. When sunlight hits the cells, it creates an electric field that allows electrons to flow, generating electricity. This electricity can then be used to power homes and businesses.
How is solar power used to make electricity?
The sunlight is collected through photovoltaic cells that acts as a conductor. When the rays hit the surface of cell they cause a release of electrons that roam freely. The panel then channels electrons into an electric field that flows in a specific direction. Then metal contacts on the top and bottom of the cells allow electricity to be used.
