How Are Solar Panels Made?

Posted on 09 November 2009

The method of making solar panels is complicated and delicate which is why there are delays in advances of solar process. However, advances in semiconductors and photovoltaic design have been made that permitted progressively more efficient and inexpensive solar cells to be developed.

Crystalline Silicon Solar Panels

The process of developing a crystalline solar panel is as follows:

  • First silicon is cut into tiny disk and than a centimeter thick. These thin,
  • Wafer-like disks are then polished and if any damage found, they are then fixed and repair.

  • Metal conductors and resources included to modify an electric charge in a semiconductor are spread everywhere in each disk.
  • Fourth step is the alignment of conductors in a very thin, grid like matrix on the top of the solar panel, and are spread in a flat, thin sheet on the side facing towards the earth.

In order to protect solar panels a thin coating is then done on the top of the photovoltaic cell. It is then attached to a substrate which is a semiconductor crystal used as a base. This attachment is done with the help of conductive cement which is quite costly. This prevents the solar panel get over heated.

Amorphous Silicon Solar Panels

Amorphous silicon solar panels are an advancement of a photovoltaic cell that is different in terms of output, structure, and manufacture than previously made photovoltaic which is made of crystalline silicon.

The improvement process of Amorphous Silicon solar panels also helps in causing less damage in transport or installation. This can help ease the risk of harming your significant investment in a photovoltaic system.

    I think some solar panels being developed in Korea have been made through recyclable materials. I’m not quite sure but the top of the matter is simple: This is good. At any rate, Solar Energy would be affordable and at the same time renewable. :D

    Thank you for the comment, i really appreciate the encouragement, and i will surely do some research about the project you mentioned about.

  3. Thanks for your sharing, whatever type of solar panels you invest, it will be return to you to cut off electrical bills at last. BTW, all people want to pay less :)
