C. Photovoltaic action

Solar cells operate on the principle of photovoltaic action, which is the conversion of light energy into electrical energy. This process involves the generation of electric current or voltage in a material when it is exposed to light. When photons (particles of light) strike the solar cell, they transfer their energy to the electrons in the material, causing them to become excited and break free from their atoms. These free electrons can then flow and create an electric current, which can be harnessed for various applications.
