Photovoltaic cell, or solar cell, is a thin and small semiconductor device, usually made from silicon, which converts light, e.g., sunlight, into electricity.The basic component of solar cells are pure silicon or crystalline compounds: Cadmium Telluride (CdTe) and Cadmium Sulfide. Cadmium Telluride is formed from cadmium and tellurium with a zinc blende. Cadmium Sulfide exists in nature as two different minerals, greenockite and hawlevite. Pure silicon, which is not pure in its natural state, is derived from such silicon dioxides as quartzite gravel or crushed quartz. These basic materials undergo chemical, thermal, and mechanical treatments to produce an excess of electrons and a deficiency of electrons respectively to make a semiconductor capable of conducting electricity. Pure silicon, for example, is treated with phosphorus and boron for this purpose.

How do you build your own homemade solar cell?

you can not made solar cell in your home. This require diffusion process and other electronic processes which are performed by costly Electronic machines so it is not poassible to make a solar cell in home without using any electronic machine.


What is Organic Solar Cell?

An organic solar cell is a type of solar cell that uses organic electronics to convert sunlight into electricity. It contains organic materials such as polymers and small molecules that are used as semiconductors to absorb light and generate an electric current. Organic solar cells are flexible, lightweight, and potentially cheaper to produce compared to traditional silicon-based solar cells.


What definition of solar cell?

A solar cell, also known as a photovoltaic cell, is a device that converts sunlight directly into electricity using the photovoltaic effect. It is typically made of silicon and generates electric current when light energy strikes the cell's surface. Solar cells are used to produce renewable energy and are a key component of solar panels for harnessing solar power.


What does the solar cell do in space?

The function of solar cell is to convert the energy from the sun into electricity. This is commonly referred to as a photovoltaic cell.

Can you remake a solar cell if you already made one that doesn't work?

Yes, you can remake a solar cell if you already made one that doesn't work. First, identify the issue causing it not to work, such as a faulty connection or contaminated materials. Then, correct the problem and try remaking the solar cell using the right materials and procedures.


What is a solar cell?

A solar cell is an electronic device that converts sunlight into electricity. An array of them is called a solar panel.


What does a solar cell need to produce electricty?

A solar cell needs sunlight to generate electricity through the photovoltaic effect, which converts solar energy into electrical energy. The cell is typically made of semiconductor materials, such as silicon, that release electrons when exposed to sunlight. These free electrons create an electric current that can be captured and used as electricity.


How much power can a solar cell produce?

That will vary a lot, depending on the size of the solar cell.
