Solar
generally we use metals and among them we use group 1 because of their lower ionisation potentials and amon them we specifically use cesium because IP decreases from top to bottom
Substance made from low work function value materials (as Sodium,Cesium etc.)
Solar
The photoelectric effect is used in devices such as solar cells to convert light energy into electrical energy. It is also used in photocells to control lighting in automatic systems, such as motion-sensing lights. Additionally, it is used in photography to capture images and in spectroscopy to analyze the composition of materials.
A lava lamp does not produce energy; it uses a combination of heat from the lamp bulb to warm the wax and density differences to create the mesmerizing lava lamp effect.
A fan typically uses electrical energy to operate, converting it into mechanical energy to produce airflow.
A slinky has potential energy when it is stretched or compressed due to its position or shape. As it moves, the potential energy is converted to kinetic energy.

The type of energy a computer uses is electricty.
That depends on the type of calculator you are referring to. An abacus uses mechanical energy An electronic calculator uses electrical energy A brain doing mental arithmetic uses chemical energy
It uses electrical energy,mechanical energy.
An automobile IS not energy; it merely USES energy.
is used in photoelectric cells.
Chemical energy.
Geothermal energy
It uses electrical energy to make thermal energy.
A lava lamp does not produce energy; it uses a combination of heat from the lamp bulb to warm the wax and density differences to create the mesmerizing lava lamp effect.
Photosynthesis is not called the photoelectric effect. The photoelectric effect is a different process where electrons are emitted from a material when it absorbs photons. Photosynthesis is the process by which plants and other organisms convert light energy into chemical energy to create nutrients.
