No. You could make a solar cell out of any chemical that has a positive photo-reaction. However metals (and more importantly, combinations of metals) have the greatest half-cell potentials that make exploiting light induced ionization potentials particularly easy in the solar cell realm of business.
Solar cells can only convert a small range of light wavelengths to electrical energy due to what is called the "band gap" of the cell material. Any light falling on to the cell whose wavelength is outside of the range of the band gap is converted to heat instead of electricity.
It is only about 0.14%.
The sun is the only source of light in the solar system. All other visible objects in the solar system are visible only because the sun illuminates them, like a flashlight.
Yes, metals do only come from ores and pure metals also are found in the Earth's crust.
The sun is the only star in our solar system.
Anything attached directly to a solar cell will only work when the cell is putting out enough energy - or if the cell is getting enough sunlight. If there is no battery or capacitor attached between the solar cell and the lamp or water pump, for example, they will only work when the solar cell is receiving sunlight.
The purpose of a solar cell is to convert sunlight into electricity. When sunlight hits the solar cell, it creates an electric current by allowing electrons to flow through the material, generating clean and renewable energy.
No. Solar and electric are two different types of energy. The only thing that can produce solar energy is the Sun.

The most powerful solar panel is the Sunpower Turnkey Solar Solution. If you are thinking of getting this, think again. This effiecient Solar Panel is only built for busieness and Government buildings.
Only the value of the metals used to make it.
Gold (Au) is an element, and is only made of itself.
It is only about 0.14%.
OUR solar system has only one star, but there are other solar systems which have more than one

Metals do not have cells and therefore do not have DNA. DNA is a complex molecule that carries genetic information and is found only in living organisms. Metals are inorganic substances and do not possess the biological processes necessary for DNA.
because the animal cell has 45 different tibula's and the human cell only has 4
