uv panels that create energy
129519
if you are referring to creating electricity from uv light then any standard photovoltaic panel will do the job.  Depending on what photovoltaic material you use the efficiency will change, but because much UV is fairly close to the visible spectrum most will give you decent collection.

I don't think so,even if there was I don't think I would them. Try using sun screen.

You're going to want something that gives your battery less than about 130 W or you'll cook it.\nThat would be about 150 to160 W panel depending on brand and how it's connected.\n\nYou may want to oversize this a bit given that your panel won't be collecting all the sun possible mounted to the back of a scooter.  If you're not overly concerned about battery life, try a 200 W panel (gotta warn you though - it ain't gonna be small)

I am not very good with optics but when I did the Science fair in school I did this project which turned out very well. It teaches about how to harness solar energy. \n\nhttp://www.energyquest.ca.gov/projects/solardogs.html\n\nThat project can actually be modified to even cook hamburgers it is a regular grill if done correctly.

No.  The opposite (emitting visible light after absorbing UV) is possible.  When light is emitted, it must have the same energy as the light absorbed, or it must have a lower energy.  UV light has higher energy than visible light, and so a material can't absorb visible and emit UV.

Not unless you can figure out a way to produce a semi-conductor at home.  Basically a solar cell (photovoltaic cell) is a couple of layers of silicon  P type and N type.  Electrons become excited when light quanta penetrates into the P layer. The excited electrons move to the N type and (very oversimplified) create electricity.\n\nI doubt you would have the facilities to create the materials at home.

If you are into electrochemistry you could make your own solar cell or a flat panel solar cell. A solar cell is a device for converting energy from the sun into electricity. This project is fairly easy and there are plenty of pics to show you exactly how its done. \n\nAlso read the first source listed first because it tells you things you need to know for the second experiment.

Some are photo electric...they turn light energy into electricity.\n\nSome are heat collectors...they store the heat and transfer it to the hot water heater.

Make a solar car, a small one albeit.

Water magnifies the power of UV rays in light.

you could use the aluminum foil to reflect the sun's rays into the box which you could cover, inside and out, with black paper. that way, it is collecting heat and the color black is the result of every color of light being absorbed and much less light reaching your eyes than something red or blue or another color. so, the black closed space would store the heat gathered by reflecting sunlight into the box\n\nHope this helps, and good luck!

No. The short wave ultraviolet is blocked by glass (I'm assuming the window is not open). For the second & third parts of your question, Yes, and No. The wavelengths needed for photosynthesis do pass through glass; and wavelengths necessary for photosynthesis are absent from normal artificial light.

If you're talking about electricity generated from solar panels, it's not widely done because of how expensive it is to build and construct panels. The material (Germanium or Silicon) alone costs a lot to synthesize.\n\nWind power turns out to be a better alternative, if you consider the costs and benefits. Ocean-tide power may be good source of power too.\n\nNow look up "Dyson Sphere." This is another aspect of tapping solar power; Solar power tapped to the extreme, not for electricity, but for life; A solution for the evergrowing population of mankind. A Dyson Sphere is impossible to construct, but a few hundred years from now it may be possible to create a Dyson Belt, a collection of inhabitable planetoids built and placed in orbit 93 million miles from the sun (the same distance as the Earth).

Not really. If we were interested in ATP instead of electricity, it might work, but even then we'd have to supply this solar cell with a fresh supply of CO2 and H2O. In this case, Physics has a better answer than Biology (the photoelectric effect)

not only saves energy, but also the monitor

It depends on the wavelength of the light and its energy.

UV light,it turns them to stone.
