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.

Is a solar cell an energy source?
A solar cell is not an energy source, but an energy converter. In the case of solar, the energy source is light, and the solar cell converts it from light energy to electrical energy.
How does a hair dryer act as an energy converter?
it is an energy converter because you are using electrical energy and converting it to heat energy when drying your hair
A device that converts light energy into electrical energy?
A solar cell converts light into electrical energy.
What changes light to electrical energy?
solar cells are used to change light energy into electrical energy
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.

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 electrical current do ships use?
Thier electrical current will be from the solar energy converter to electricity.
Does light intensity affect electrical energy?
The more electrical energy there is there is more power or wattage which means that the light intensity is higher if there is more electrical energy.
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?
Electrical energy gets converted to light and heat energy.
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.
