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.

Which parts of the solar system make their own light?
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.
What percentage of the mass do the planets make up in your solar system?
It is only about 0.14%.
Can you explain why solar cells only collect about 15 percent of Sun's energy?
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.
What organelles make energy for the cell?
Mitochondria- animal and plant cells Chloroplasts- only plant cells in the animal cell, the mitochondria converts sugars and fats (glucose) into energy (ATP). in the plant cell, the chloroplasts convert solar energy into glucose, then the mitochondria converts the glucose into energy.
Do metals only come fron ores?
Yes, metals do only come from ores and pure metals also are found in the Earth's crust.
How could a lamp or water pump work at night using a solar cell?
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.
What is the purpose of the solar cell?
To provide electrical current flow using only sunlight.
Can electricity make solar energy?
No. Solar and electric are two different types of energy. The only thing that can produce solar energy is the Sun.
What are the most efficient solar panels?
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.
Is any one using solar energy?
We all are using solar energy directly or indirectly. Using solar energy doesn't only means using solar cell or solar heaters etc... but food is also a byproduct of sunlight, when we dry our clothes and grains insunlight it also a use of solar energy.
Is the sun just one of stars that make up your solar system?
OUR solar system has only one star, but there are other solar systems which have more than one
What percentage of the mass do the planets make up in your solar system?
It is only about 0.14%.
Which parts of the solar system make their own light?
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.
Which metals are used to make gold?
Gold (Au) is an element, and is only made of itself.
How much is a gold plated nickel worth?
Only the value of the metals used to make it.
How did Mercury's location in the solar system affect its composition?
Mercury is rich in metals because only metallic grains could survive the high temperatures so near the Sun.
Why does a cell wall not make sense in animal cell?
because the animal cell has 45 different tibula's and the human cell only has 4
