PV panels are made up of treated silicon and other materials including an antireflective coating. The silicon is a semi-conductor (like metal, not like plastic). When the light hits the silicone semi-conductor, a portion of the energy is absorbed by the panel and knocks electrons in the silicon loose which allows them to flow freely. The PV panels have an electric field that forces these 'freed' electrons to flow in a specific direction - and we all know that electrons flowing in a specific direction is known as 'current'.

What energy changes take place in a solar cooker?
In a solar cooker, solar energy (light and heat) is absorbed by the reflective surface and converted to heat energy. This heat energy is then transferred to the food in the cooker, causing it to cook or heat up.
How is solar energy converted from mechanical energy to electrical energy or collected as heat?
Solar energy can be converted into electrical energy using photovoltaic cells, which convert sunlight directly into electricity. On the other hand, solar energy can be collected as heat using solar thermal systems, where sunlight is used to heat a fluid that produces steam to drive a turbine and generate electricity.
What type of energy resource is solar energy?
Solar energy takes the form of radiation. Solar panels may allow this solar energy to be converted to heat or to electricity. (Electricity is not a fuel or even energy: it is a means of transferring energy).
What is the energy transformation taking place in solar cooker?
Radiant energy -> electrical energy -> thermal energy
How does solar energy differ from heat energy?
Solar energy is energy from the sun that is converted into electricity using solar panels, while heat energy is the total amount of kinetic energy due to the motion of molecules in a substance. Solar energy harnesses the sun's rays to create electricity, while heat energy is a form of energy associated with the temperature of an object or substance.

What is the name of the energy that comes from the sun?
Solar energy is the energy that comes from the sun. It is a renewable and sustainable source of power that can be converted into electricity or heat for various applications.
Is the thermal energy an example of the solar energy?
the solar energy is the energy of sun and sun gives light and heat but the thermal energy is only a heat energy but radiant energy is light and heat energy so the answer will be no and the correct answer will be radiant energy
