Monocrystalline Solar Cells, Size Of 125*125mm 2BB, High Efficiency
1> Quick Detail:
2> Description:
A single-crystal silicon - often made using the Czochralski process - mono-crystalline wafer cells are generally expensive.
The expense arises as mono-crystalline wafers are cut from cylindrical ingots.
As a result, the silicon wafers do not entirely cover the surface of a square solar cell module without a substantial waste of refined silicon. Hence most mono-crystalline panels have uncovered gaps at the four corners of the cells.
Once the solar cell is fabricated, that is, once it has been either grown or the layers of the solar cell have been deposited onto each other, and you’re looking at a wafer, the front and back contacts need to be added to give the electron-hole pairs a place to go and complete the photoelectric effect… That is, wires need to be added to allow current to flow!
This is a place where things get tricky and lots of research is being done, because when the deposition of a metal layer onto a crystal is done, at the boundaries between the two materials a resistance exists that is generally larger than the resistance inside the homogeneous material itself. The research is to reduce this resistance with various theories and tricks.
Each solar cell wafer is generally combined into one big solar panel, which is most likely what you buy in the stores. These are usually all wired up, and ready for you to plug into a battery!
