solar cells directly convert solar energy to electricity... if thats what you are asking about, then yes. if not, clarify your question.
Yes.
Solar cell
Solar energy.
How is mechanical energy is converted to electrical energy through a solar cell? It isn't, what energy is converted is commonly known as solar energy. What happens in a solar cell is that the sun "shoots" photons at the silicon cell. When the photons are shot hard enough, the silicon "breaks" as well as the photon and energy is formed. This is then used as electrical energy.
a photovoltaic cell or solar panel
A solar cell is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect.
That'd be a photovoltaic cell.
In short, the light (electromagnetic energy) shining on the solar cell is converted directly to electric charge (potential energy). The increase in the electric charge can promote the flow of electric current in an external circuit, in much the same way as an ordinary electrical battery would.
PV cells are the correct term for a cell that converts solar energy directly to electric energy http://en.wikipedia.org/w/index.php?title=Photovoltaic&redirect=no
A solar cell is not an energy source, but an energy converter. In the case of solar, the energy source is light, and the solar cell converts it from light energy to electrical energy.
there are two main ways. the first way is to use the light to boil water and turn it into steam that turns a turbine that creates electricity. the other way is to convert it directly into electricity using a solar cell (or solar pannel.)
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.
