internal combustion engine
electric motor
photovoltaic cell
AC generator

Answer 1

The answer would be photovoltaic cells.

Answer 2

The correct answer is option C, photo voltaic cell

Step-by-step explanation:

The photo voltaic cells are devices used for producing electricity with the use of solar energy. It works when photon or the particles of light get excited on exposure to sun light and free electron are released which leads to the generation of electric current. A photo voltaic cell is made up of two silicon plates that sandwiches some other material in between just like a normal semiconductor.
