can you tell me which one is better according to power produced?
They are too expensive ,and the pay out will probably not be very good. Note of caution !! mount them very sturdy as they have a lot of surface so a little wind can tare them up.

Solar cells/solar panels are environment friendly, but at the moment other sources of electrical energy are cheaper than solar power. How can we make solar cells more efficient and cheaper?
Every solar cell has a maximum theoretical efficiency. It is a property of that cell, and no matter the conditions it cannot be any higher. The most efficient one, to date, is ~35%. Factoring in material and system limitations, the maximum efficiency

Can any type of solar cell/solar panel convert light into electricity instantaneously? It does not matter if the amount of electricity is extremely small or not, just as long as it can be detected immediately. Is this possible?
at the speed of light
I am doing a project on the energy usage of solar cells. Other than pollution, because it is a category in itself, what are the environmental factors when using solar cells?
You don't have to use special water to clean rooftop solar panels. You can just hose them down.
Other than what was already said (temperature, pollution), weather of course. Solar cells are only 50% of their full capacity when it is...
The cable charger brick thing says 100-240v 50-60hz 1.5A input.The output is 19v and 3.95A
I was planning on using the solar cells out of the outside lamps that line the walkways ot houses.
well that might get expensive. see you have solar power, which is direct current (dc) power that needs to be converted into alternating current (ac) power then back to dc power. so you will have to have power inverters and monitors and all that stuff
Does anyone know the range of frequencies or wavelengths? I'm thinking mostly of common silicon solar cells. If anybody knows where a plot of current vs frequency is that would be great too. Thanks.
For first generation solar cells they produce current at the sunlight wavelengths. See graph from the link. You can probably find a current vrs. frequency plot somewhere but certain things have to be fixed for this to occur such as the incidence...

Trade war with China could claim US solar industry jobs as a casualty
Six decades ago, Gen. Omar Bradley warned that expanding the Korean War into China would be "the wrong war, at the wrong place, at the wrong time, with the wrong enemy." Now the same could be said about the trade war that is brewing with China in the solar energy industry.
Cutting off China and threatening U.S. solar jobs started in October when a German company with a manufacturing facility in Oregon filed a trade complaint with the U.S. International Trade Commission and the Department of Commerce demanding that punitive tariffs be imposed on solar panels and cells imported from China. Just before New Year's Day, several U.S. manufacturers filed a similar petition against China and Vietnam seeking special surcharges on wind towers imported from these countries.
MIT Prints Solar Cells onto Paper
Stands in front of yet another solar innovation . If scientists can raise conversion efficiencies to commercially competitive levels, their product could revolutionize the solar industry. So far, efficiency lags at between 1.5 and 2 percent, although their quest is eased somewhat by simple and inexpensive production. In other words, they don’t have to hit 20 percent efficiencies that rival monocrystalline silicon solar panels because the latter are expensive to produce and install.
Regardless of progress yet to be made, last week’s unveiling of MIT’s paper solar cells is the first of its kind and a momentous occasion in solar power history . How momentous exactly remains to be seen. Driving their momentum is the scientists’ ability to print the solar cells onto paper using a process similar to that of an inkjet printer. So making solar cells in the future could be as easy as printing out your child’s book report (although it’s doubtful we’ll all be printing solar cells in our living rooms). MIT scientists hope that one day the same process could be used to print cells onto plastic or foil.
