Solar Power?

Question

If you magnify light onto a solar cell, will the power output be greater??

Answer 1

Yes, up to a point. Especially if the sunlight is weak to begin with.

However, beyond a certain point you begin putting too much heat energy into the cell and the cell cannot get rid of that heat fast enough, so it overheats and fails.

Answer 2

The voltage created by solar energy is a function of the surface area of the solar panel.

When you magnify the light, you are focusing it on a smaller area, although the energy would indeed be higher.

There's probably some equations out there that can be used to maximize solar panel output as a function of photon energy and surface area.

Answer 3

Yes, they experiment with this technology in Israel. They have some field where they focus the sunlight from all these mirrors to a solar cell panel. That country requires by law that ever housing unit uses solar power for the water heater.

Answer 4

Yes it's
photons from the sun (solar light) into electricity. In general, a solar cell that includes both solar and nonsolar sources of light (such as photons from incandescent bulbs) is termed a photovoltaic cell. Fundamentally, the device needs to fulfill only two functions: photogeneration of charge carriers (electrons and holes) in a light-absorbing material, and separation of the charge carriers to a conductive contact that will transmit the electricity. This conversion is called the photovoltaic effect, and the field of research related to solar cells is known as photovoltaics.

Solar cells have many applications. Historically solar cells have been used in situations where electrical power from the grid is unavailable, such as in remote area power systems, Earth orbiting satellites or space probes , consumer systems, e.g. handheld calculators or wrist watches, remote radiotelephones and water pumping applications. Recently solar cells are particularly used in assemblies of solar modules (photovoltaic arrays) connected to the electricity grid through an inverter, often in combination with a net metering arrangement.

Solar cells are regarded as one of the key technologies towards

Answer 5

Yes. It's similar to setting fire to paper with a magnifying glass.

Answer 6

yes

Answer 7

Until destruction? No
