Solar Cells Material Types, String Ribbon and Amorphous


<< Continue from previous page

String Ribbon

This type of solar cells material is created by pulling a molten silicon mass into a thin film then letting it cool down to crystallize, then is doped. The solar cells manufactured with this process are less expensive than those manufactured with the mono and polycrystalline materials process. The efficiency of cells made with this kind of material is in the order of 7% to 8% and the yearly degradation is in the range 0.25% to 0.50%, very similar to mono and polycrystalline materials.



Amorphous Also Called Thin Film

In this process the silicon material is vaporized over a plate of stainless steel, glass or other similar materials,  this process is faster and more economical than the ones used for monocrystalline, polycrystalline and ribbon materials. One advantage of this material is that the modules can be made flexible and suited for mobile application such on RV or other application that requires mobility, the main drawbacks of this technology is the faster yearly degradation of more than 1% and the lower efficiency in the order of 5% to 7.5%, it visual appearance is almost black.
