A solar cell converts light energy into electricity. It is basically a giant semiconductor junction laid flat (fabricated) on a panel. One lays the panel to face the sunny side. With an inverter, the DC can be converted to AC to power household electrical appliances. One can also hook the panel up to a battery and store the energy for later use.

Solar cells are used to turn sunlight into?
It comes out as direct-current electric power.
How does electric current work in solar panels?
Understanding the intricacies of how electric current works in solar panels involves delving into the fascinating process of converting sunlight into usable electrical energy. At the heart of this transformation is the photovoltaic effect, a phenomenon inherent to the solar cells comprising solar panels. The solar panels predominantly consist of semiconductor materials, typically silicon-based, that exhibit the photovoltaic effect. When sunlight strikes these materials, photons, the particles of light, transfer their energy to electrons within the semiconductor. This energy excites the electrons, enabling them to break free from their atomic orbits. This liberation of electrons results in the creation of electron-hole pairs within the semiconductor. An electron-hole pair comprises a free electron and the positively charged "hole" left behind when an electron is excited. These electron-hole pairs are pivotal for the generation of electric current. Due to the presence of an electric field within the solar cell, the liberated electrons are compelled to move in a specific direction, establishing an electric current. This movement of electrons constitutes direct current (DC). The electric field is established during the manufacturing process through the introduction of specific doping materials. Conductive metal contacts on the top and bottom surfaces of the solar cell facilitate the collection of the generated electric current. The electrons flow through an external circuit, creating an electric current that can be harnessed for various applications. While solar panels produce DC, most household appliances and the electrical grid operate on alternating current (AC). Therefore, an inverter is typically employed to convert the DC generated by the solar panels into AC, making it compatible with standard electrical systems. In conclusion, the generation of electric current in solar panels relies on the photovoltaic effect, where sunlight triggers the liberation of electrons, setting in motion a series of processes that culminate in the production of clean and renewable energy.
Devices that convert the sun's energy into electrical energy?
The device which convert sun's energy into electrical energy is called solar battery. The artificial objects which uses solar batteries are mostly in space. The aircraft Solar Impulse 2 flied arround the world driven by solar batteries.
What happens to the energy in a solar panel?
Photons of light (energy) are absorbed by the silicon atoms of the solar panel, resulting in an ejection of electrons proportional to the frequency of the photons absorbed. This is called the photoelectric effect. As a large number of electrons are being ejected from atoms and set into motion, this generates an electric current. It is this electric current that can be used to power devices.
What word is for the definition the kind of cells used to turn sunlight into electric current?
It is called a photovoltaic cell, also called solar cells.
Why solar panels generate dc current?
Because it creates solar power
How does solar cell get its energy?
when the sun hits the solar panel it creates a current
What device can provide the energy for an electric circuit?
A battery, generator, or solar cell can.
Does a photovoltaic cell produces AC electric current?
The panel itself produces DC and if it is connected to mains electricity it needs a separate converter to change the current to AC.
What type of electric current is produced by fuel cells and solar cells?
ac
What uses motion to produce an electric current?
Any electrical generator except solar.
Materials of solar power?
In a crystalline solar electric panel, the light of the sun interacts with a semiconductor material (usually silicon) in the PV cell to free electrons and produce an electric current.
Solar cells are used to turn sunlight into?
It comes out as direct-current electric power.
What causes solar power?
Sun is the main cause of solar power.When sunlight hits a solar cell, also known as a photovoltaic cell, that energy can be transformed into electric current.
What is the working of solar engine for solar car?
A solar engine for a solar car is actually an electric motor. Solar cells on a solar car collect solar energy, which is then sent to a battery or battery pack in the form of DC current. This energy is then used to power the solar car.
Is solar and photovoltaic the same thing?
It really is. A tiny solar panel collects sunlight, which then creates an electrical current. This current passes through a tiny electromagnet, which cause a switch to be held open so that power can't get to the light. When the sun goes down, power is no longer being created at the solar panel, which in turn causes the electromagnet to stop being magnetized. This causes the switch to close, which then cause current to flow to the light.
What is the energy transformation of an electric gate with a solar panel?
Well, it would be solar to electric. Right? Because if the way to operate a gate has a solar panel, but the gate is electric, it would be solar to electric.
