Correct Answer: Electrical energy

Solution : The correct option is electrical energy.

The photovoltaic effect is a mechanism used by photovoltaic cells, also referred to as solar cells, to transform light energy from the sun directly into electrical energy. When photons, the light particles hit a solar cell's surface, their energy is transferred to the material's electrons, causing this effect.  These electrons get activated by the energy of the photons, which causes them to flow as an electric current. The generated current can then be harnessed and used to power electrical equipment, or it can be stored in batteries for later use.
