The type of object is called a photovoltaic cell, or photocell. Light photons are absorbed and used to excite electrons, providing electric current.
The devices used to convert sunlight are called solar panels, or solar arrays.
Solar panels use two conductive plates, anode and cathode, and a semiconducting layer which has electron holes created by an impurity. Impurities are necessary to break up the crystalline structure of sillicon and send the electrons flowing through the material.
When photons (packets of light energy) hit the solar panel, they knock the free electrons into the conductive plate creating a current. This is where the inefficiencies lie, because some photons just go right through and miss the electrons, or are reflected.

∙ 6y agoThat sounds like a good description of a light bulb.
Note that there are other things that convert electrical energy to light energy including electric arcs such as those in arc welders (light is a byproduct of the main purpose of the arc) and stove elements (you can see them get red and give off light as they get hot),
The light is released as the electrons in the atoms decay from higher energy orbitals to lower energy orbitals, releasing some energy in the form of photons.

Does light bulb converts kinetic energy into electrical energy?
No, a light bulb does not convert kinetic energy into electrical energy. Light bulbs rely on electrical energy to produce light. The kinetic energy of moving objects is not directly converted into electrical energy to power the light bulb.
Name two common energy conversions involving electrical energy?
Electrical energy to light energy: When electrical energy is passed through a light bulb, it is converted into light energy, allowing the bulb to produce light. Electrical energy to heat energy: When electrical energy flows through a resistor or heating element, it is converted into heat energy, which can be used for various applications such as heating water or a room.
What type of energy transformation occurs when a light bulb is turned on?
Electrical energy is transformed into heat and light. More specifically, electrical energy from the household wiring is turned into thermal energy (heat) by the filament which in turn becomes luminous energy (light). Some energy is lost due to resistance in the conductors.
What energy transformations take place when electrical energy is applied to light bulbs?
When electrical energy is applied to light bulbs, the energy transformation involves converting electrical energy into light and heat energy. The electrical energy flows through the bulb's filament, heating it up and causing it to emit light. Some of the electrical energy is also converted to heat due to resistance in the filament.
What is the transformation of light enery?
Light energy can be transformed into other forms of energy such as heat, electrical energy, or chemical energy. For example, solar panels convert light energy from the sun into electrical energy, while incandescent light bulbs transform electrical energy into light and heat energy.
Is a solar cell an energy source?
No, a solar cell is a device that converts sunlight into electricity. It is one component of a solar energy system that utilizes the sun as an energy source.
How does a hair dryer act as an energy converter?
A hair dryer converts electrical energy into mechanical energy to produce airflow, and then into thermal energy to heat the air. The electrical energy from the outlet powers the motor that drives the fan to create airflow, and the heating element generates heat to dry hair.
5 examples of transformation of energy?
TV- Electrical energy to light and sound energy Radio and stereo - Electrical energy to sound energy Fan- electrical energy to mechanical energy Toaster - Electrical energy to heat energy Light bulb- Electrical energy to Light energy Battery or cell - Chemical energy to electrical energy
What changes light to electrical energy?
Photovoltaic cells, commonly known as solar cells, convert light energy into electrical energy through the photovoltaic effect. When photons from sunlight hit the cell, they knock electrons loose from atoms, generating an electric current.
A device that converts light energy into electrical energy?
A photovoltaic cell, also known as a solar cell, is a device that converts light energy into electrical energy. This process occurs through the photovoltaic effect, where photons from light interact with the semiconductor material in the cell to generate an electric current. Solar panels consist of multiple photovoltaic cells connected together to capture and convert sunlight into usable electricity.
What type of energy transformation occurs when a light bulb is turned on?
Electrical energy is transformed into heat and light. More specifically, electrical energy from the household wiring is turned into thermal energy (heat) by the filament which in turn becomes luminous energy (light). Some energy is lost due to resistance in the conductors.
What electrical current do ships use?
Thier electrical current will be from the solar energy converter to electricity.
Does light intensity affect electrical energy?
Yes, light intensity can affect the amount of electrical energy produced in devices like solar panels. Higher light intensity typically results in greater energy generation, as more photons are available to be converted into electricity. Conversely, lower light intensity can lead to reduced electrical output.
What are examples of electrical loads in the kitchen that convert electrical energy to light energy?
light bulbs switches
What energy transformations take place when electrical energy is applied to light bulbs?

When a lamp is turned on electrical energy changes into what form of energy?
The older generation of bulb(one in witch heating metal coil was used) convert electrical energy into both heat and light energy and consume more energy as some energy is lost as a heat energy. The newer generation of electrical bulb (C.F.L.) convert almost all electrical energy into light energy and consume much less electrical energy.
Is electric energy converted to heat energy or light energy?
Yes, electrical energy can be changed into thermal (heat) energy. Light is electromagnetic energy, and electricity can be changed into light energy. We know that a resistance heater changes electrical energy into thermal energy. An electric range does this, as does an electric space heater. We see electrical energy changed into light in fluorescent lights.
