Dear Atik

What I understand from your question is that you want to know the ways to use photon energy as renewable energy.

1- The photon energy is used for photocatalytic water splitting to produce hydrogen gas, which is an important energy carrier

2- The photons energy is transferred to electrons in the DSSC which directly converts solar energy to electricity with a higher efficiency that the traditional solar cells

3- the Solar cells which contain a semi conductors converts the photon energy to electricity

4- The Solar energy is concentrated and converted to laser beam (solar-pumped laser)

And many other applications

Regards,

Several Applications about using photon energy in renewable energy such as solar cells.

Looks like an interesting topic. Could you please explain the question bit more precisel?
