For instance, a calculator using a solar cell will work in artificial light with no sun (I think). How efficiently would that run? What kind of bulb would be best?
It depends on what sort of solar cell you are using. Different materials respond differently to different spectrums of light. If your talking about the solar cell in your calculator then I would assume its designed to work best under typical...
Check out a one-minute animated video that shows how a solar cell converts sunlight into electricity.
Hi, can anyone please tell me how solar cells work? Not in too much detail with alot of compicated terminology. I just need to know how they convert solar energy into electrical energy without all the complicated stuff.
Thanks...
Detailed Version: A solar cell is composed of a semiconductor with n-type and p-type material, that has a built-in potential at the junction. When light photons hit the semiconductor, they are absorbed and convert the photons energy into an...

I'm not a chem or engineer buff, so the simpler the answer, the better. I know good amount about solar technology, but i can never find a simple answer to the question.
The method is the same as that in a regular silicon solar cell. In other words, the material will be doped on one side of a junction to have extra electrons and on the other side to have fewer electrons. The junction will be set to absorb a...

Solar cells take years to pay for themselves but you never have to worry about power outages. I have been considering solar shingles which are less bulky than the roof panels. They cost about as much as a Honda but you never have to pay for...
So basically, to convert solar energy to electrical energy, I am dealing with Photovoltaics? And am i right in understanding that some materials such as silicon have properties where when exposed under certain light, they release electrons,...
Solar cells are a sandwich of N type and P type silicon. The N type has excess electrons (Negative) after the atoms have bonded and the P has a deficiency of electrons (Positive) to form bonds.
At the junction, it forms a depletion...
I'm doing a little project for fun making a bunch of pages explaining solar technology. I put up a page explaining how a solar cell works, but I would like some people to look at it and tell me if it is easy to understand or not. Also if there...
I've just read you're page on solar cells and I must admit I found it extremely clear and easy to understand,mind you I did get higher physics so it is familiar territory but I certainly think someone who hasn't a great knowledge of science would...

“In this project we hope to use branching fractals – the type found in leaves and trees – to optimize the collection of sunlight, while reducing the cost of doing so,” Ilan said.
The researchers are actually tackling two different projects, he said. The first is to create organic photovoltaic cells that rely on nanoscale fractal pathways for the direct conversion of sunlight to electricity.
The term “organic” refers to carbon-based molecules, which are generally very common, and hence, inexpensive. “Nanoscale” refers to the realm of the very small, a true nanoscale device is generally thought to be around 100 nanometers or less in size. A nanometer is one billionth of a meter, roughly the equivalent of a marble compared to the earth.
Understand How a Solar Panel Work — SelfSufficiency
Before you attempt to install a DIY solar panel into your home, it will be wiser to find out how do solar panels work so that the entire procedure will be much easier to handle. The process begins with solar modules. They are the main components being exposed to the sunlight. Their main aim is to convert the sun’s energy into usable electrical power for your appliances. To get it correctly installed, solar modules are to be mounted on a steel frame and positioned onto your rooftops.
Power being produced by the solar modules is converted from Direct Current (DC) to Alternative Current (AC) via the power converter. In general, Alternating Current (AC) is the usable electrical power that we require to power our appliances.

Though CSP can be more efficient in trough or mirror aperture, they end up being spread apart and less dense than typical PV, so are less efficient per total area. With panels approaching the $1/W cost, they don't even need to be positioned optimally.
