What is the science behind solar energy?

Answer 1

light = enregy..... heat = energy...simple.....you can make nano cells that do these also nano cells that can create energy by sound vibrations... i need some science "geeks" to help me devolop easy advances in these areas... if your interested contact me @ bengammonhardaway@ymail.com .....also have a few ways of making free electricity

Answer 2

The science behind nuclear energy involves getting the atomic nuclei of atoms to undergo changes and release energy. We know that setting conditions involves finding materials that will, under the right circumstances, undergo fission or fusion and "rearrange" their atomic nuclei. The fission or fusion reactions release energy that we can use. Currently we can only use fission effectively to generate energy. (We left out thermonuclear fusion weapons.) Let's look a bit further.

If we gather some fissionable material like uranium, we can set up a machine in which we can cause it to undergo fission. A nuclear reactor is that machine. If we permit a critical mass to be achieved, a fission reaction will begin, and we can sustain this reaction to continuously release nuclear energy. Most of the useful energy released in the nuclear reactions appears in the form of heat, and we can pump coolant around inside the reactor, we can collect that heat. The thermal energy can be used to boil water to make steam, and the steam can be used to spin conventional steam turbines.

Nuclear energy is converted into both thermal and mechanical energy as atoms "break up" in the fission reactions. The mechanical energy is converted into thermal energy in the fuel elements, and that heat is carried off via the coolant to steam generators. The thermal energy is converted into mechanical energy in the turbines, and the turbines spin generators. The mechanical energy of the spinning generator is converted into electromagnetic energy, and we see that as electricity that we can distribute to points of use.

Answer 3

Solar energy is generated when sunlight is converted into electricity using photovoltaic cells or concentrated solar power systems. Photovoltaic cells create an electric current when sunlight hits the semiconductor material they are made of, while concentrated solar power systems use mirrors or lenses to concentrate sunlight onto a small area to produce heat, which is then converted into electricity. This process is a clean and renewable source of energy as it relies on the sun's abundant and sustainable energy output.

Answer 4

Solar panels are layers of semi-conductors that excite the electrons to create the electricity.

Answer 5

This is exactly the same as "the science" for all other Scientific Endeavours - OBSERVATION.

Answer 6

Electromagnetism, initially, but Quantum Electro-dynamics (QED), ultimately.

Answer 7

its a plastic or fiber sheet to maintain the temperature of plants
