Dear colleague Diman m,
Have a nice time and good day.
Of course single crystal is better it has: no defects, known structure, long range order
High sensitivity,......etc. in some cases we need for doping, so the transformation between amorphous- poly crystalline - crystalline states is necessary.
dear Diman
in solar cell
Polycrystalline
Polycrystalline material – Aggregate of several crystals or grains ØThe boundary between the grain is the grain boundary across which the orientation of the crystal changes. ØThe point at which three boundaries meet is called the triple junction.
Polycrystalline thin-film cells are made of many tiny crystalline grains of semiconductor materials. The materials used in these cells have properties that are different from those of silicon.
Multicrystalline silicon devices are generally less efficient than those of single-crystal silicon, but they can be less expensive.
Polycrystalline solar panels tend to have slightly lower heat tolerance than monocrystalline solar panels. This technically means that they perform slightly worse than monocrystalline solar panels in high temperatures. Heat can affect the performance of solar panels and shorten their lifespans. However, this effect is minor, and most homeowners do not need to take it into account.
A single crystal or monocrystalline solid is a material in which the crystal lattice of the entire sample is continuous and unbroken to the edges of the sample, with no grain boundaries
In Solar Pannel
Ø Monocrystalline solar panels have the highest efficiency rates since they are made out of the highest-grade silicon
Ø Monocrystalline solar panels are the most expensive.
Amorphous
Amorphous – random arrangement of atoms: Silicate glass, Polymers
The word “amorphous” literally means shapeless. The silicon material is not structured or crystalized on a molecular level, as many other types of silicon-based solar cells are.
heses are the two major reasons why amorphous silicon solar cells have a great potential to one day become cheaper than mono- and polycrystalline solar cells.
Can be made flexible and lightweight. A flexible thin-film module enables us be much more creative when it comes to applications
Amorphous thin-film solar cells have lower efficiency rates. The technology is new, and efficiency rates are thought to increase with technological breakthroughs in the near future.
Thank you so much my friend sh.A.Kakil your answer have more information
Dear Diman,
I hope you are doing well..
My respect to all above good answers.Additionally, in general view most devices like you have mentioned are responsible to change radiation to electric pulse so single crystal is better than poly crystal and amorphous to do this process with low error because of those above properties.
