Solar Power Cell Phone Charger
Batteries are old-school stars of gadget world
If batteries could go to a party they'd wear blue suits and brown shoes and stand in a corner while the HDTVs and PCs whooped it up. But without them your iPhone wouldn't say a word, and your laptop computer might as well stay home.
Solar Panels Successfully Developed A New Coating
The U.S. in 2008 Rensselaer Polytechnic Institute researchers have developed a new type of coating, its coverage in the solar cell panel, which allows the sunlight absorption rate increased to 96.2%, while the ordinary solar panels absorb sunlight rate was only about 70%.
The new coating is mainly to solve two technical problems, first, to help solar panels to absorb almost all of the solar spectrum, the second is to make solar panels solar mobile charger absorb sunlight from a larger perspective, thus enhancing the solar panels to absorb sunlight, efficiency.
Ordinary solar panels generally only absorb part of the solar spectrum, but usually only in the absorption of direct sunlight when the work more efficient, a lot of solar energy devices are equipped with automatic adjustment system to ensure that solar panels and always maintain the most conducive to absorption of the sun energy point of view.
Multi-compound solar cells
In addition to commonly used single-crystal, polycrystalline, amorphous silicon cells, the multi-compound solar cell that is not a single element made of semiconductor materials, solar cells. There is now a wide variety of studies, most yet to industrial production, mainly in the following categories:
a) CdS solar cells
b) GaAs solar cells
c) copper indium selenide solar cells (a new multi-band-gap gradient Cu (In, Ga) Se2 thin-film solar cells)
Solar power system design needs to consider the following factors:
Question 1, where the use of solar powered cell phone charger generation system? The way solar radiation situation?
Question 2, the system load power be?
Question 3, the system's output voltage is the amount of DC or AC?
Question 4, the system need to work how many hours a day?
Question 5, in the event there is no sunlight in rainy weather, the system must supply the number of consecutive days?
Question 6, the load situation, purely resistive, capacitive, or inductive, starting current be?
Question 7, the number of system requirements?
