What are solar photovoltaic cells?

We Answered:

A solar cell is a device that converts the energy of sunlight directly into electricity by the photovoltaic effect. Sometimes the term solar cell is reserved for devices intended specifically to capture energy from sunlight, while the term photovoltaic cell is used when the light source is unspecified. Assemblies of cells are used to make solar panels, solar modules, or photovoltaic arrays. Photovoltaics is the field of technology and research related to the application of solar cells in producing electricity for practical use. The energy generated this way is an example of solar energy (also called solar power).

what will the future hold for photovoltaic cells. is it a good as it well get or will it be better?

We Answered:

photovoltaic is excellent. the problem still is that it is expensive.
the prices will go down as soon as the demand and therefore
the production increases.

Photocells and photovoltaic cells?

We Answered:

Structurally, it is common for photocells to be made from cadmium sulfide, and for photovoltaic cells to be made from silicon.

"Photocell" usually means a Light Dependent Resistor (LDR). It's a device whose electrical resistance changes with the amount of light present. Since resistors do not generate a voltage or current by themselves, a separate power supply is required for a photocell to be useful. They are usually used like a switch, to turn a circuit on or off when the amount of light is above or below a preset level.

Photovoltaic cells do generate a voltage or current which increases according to the amount of light present. People are often referring to solar cells, which convert light into electrical power, when they say "photovoltaic cell". A photovoltaic cell may also refer to a photodiode, which outputs a small electrical signal that may be used as a measure of the light level.

Hope this helps.

what is the importance of seperator in the photovoltaic cells?

We Answered:

A separator keeps the anode and cathode apart to prevent metallic conduction and is usually porous and holds some if not all of the electrolyte. It allows ionic current to flow through it so that it does not impede the operation of the cell
