The idea of solar power for remote computing is finally catching on. It is working for everyone from the cross-country cyclist and weekend camper, to regular working stiffs that have to rough it on the job.Also it allows everyone to use their laptop at many place for longer times.But how it works?
The application is simple and we can see them already apply in previous technology.For example,the solar cells that you see on calculators and satellites are photovoltaic cells or modules (modules are simply a group of cells electrically connected and packaged in one frame). Photovoltaics, as the word implies (photo = light, voltaic = electricity), convert sunlight directly into electricity. Once used almost exclusively in space, photovoltaics are used more and more in less exotic ways. They could even power your house.
Photovoltaic (PV) cells are made of special materials called semiconductors such as silicon.When light strikes on the material,it will absorbed the energy and transfered to the semiconductor.The energy knocks electrons loose, allowing them to flow freely.the PV cells has magnetic fields that wiil allow the energy to flow in a certain direction and produces cuurent.The Application need to be corresponded with the power consumption of laptop.This current, together with the cell's voltage (which is a result of its built-in electric field or fields), defines the power (or wattage) that the solar cell can produce."
