Which energy transfer occurs in photovoltaic solar panels? A. heat energy changes to electrical energy
B. electrical energy changes to light energy
c. electromagnetic radiation changes to electrical energy
O D. electromagnetic radiation changes to heat energy

The photovoltaic solar panels transfer the heat energy into electrical energy. This means that the sunlight energy gets converted into electricity.  

Photovoltaic cells needed an electric field to function. A magnetic field is created when contrary poles are separated, and an electric field is created when opposite charges are detached.

They do this by seeding phosphorous into the top layer of silicon, which adds extra negative-charged electrons to that layer. Meanwhile, boron is added to the bottom layer, resulting in fewer electrons and a positive charge.

All of this adds up to an electric field at the silicon layer's junction.

Therefore, the correct option is A.

It is this effect that makes solar panels useful, as it is how the cells within the panel convert sunlight to electrical energy.
