My answer
Photochemical

Am I right?

No. Photochemical is an adjective. You need a noun for that blank.

solar pannle

Yes, you are partially correct. The tool used to capture the energy in sunlight is called a solar panel or a photovoltaic (PV) panel. Solar panels are made up of solar cells, which are typically made of photoelectric materials such as silicon.

The process by which solar panels capture sunlight and convert it into usable energy is known as photovoltaics. When sunlight hits the solar cells, it excites the electrons within the material, allowing them to flow as an electric current. This electrical current can then be used to power various devices or can be stored in batteries for later use.

So, while the term "photochemical" can be related to solar energy, it generally refers to chemical reactions triggered by light rather than the capture of solar energy itself.
