Production of Solar Panels

Making solar panels is a delicate process, and that major solar advances did not come into play until the last quarter of the last century, when advancements in semiconductors and photovoltaic design allowed increasingly efficient and affordable solar cells to be developed.

Crystalline Silicon Solar Panels
The creation of solar panels typically involves cutting crystalline silicon into tiny disks less than a centimeter thick. These thin, wafer-like disks are then carefully polished and treated to repair and gloss any damage from the slicing process. After polishing, dopants (materials added to alter an electrical charge in a semiconductor or photovoltaic solar cell) and metal conductors are spread across each disk. The conductors are aligned in a thin, grid-like matrix on the top of the solar panel, and are spread in a flat, thin sheet on the side facing the earth.
To protect the solar panels after processing, a thin layer of cover glass is then bonded to the top of the photovoltaic cell. After the bonding of protective glass, the nearly-finished panel is attached to a substrate by expensive, thermally conductive cement. The thermally conductive property of the cement keep the solar panel from becoming overheated; any leftover energy that the solar panel is unable to convert to electricity would otherwise overheat the unit and reduce the efficiency of the solar cells.
Despite these protective measures against the tendency of solar panels to overheat, it is vital that when installing a solar panel, additional steps should be taken to ensure the solar panel is kept cool. Elevating the solar panel above ground to let the airflow underneath cool the device.

Another type of solar panels will be the amorphous silicon solar panels. They are powerful, emerging line of photovoltaic that differs in output, structure, and manufacture than traditional photovoltaic which use crystalline silicon. Amorphous silicon solar cells (A-si cells) are developed in a continuous roll-to-roll process by vapor-depositing silicon alloys in multiple layers, with each extremely thin layer specializing in the absorption of different parts of the solar spectrum. The result is record-breaking efficiency and reduced materials cost (A-si solar cells are typically thinner than their crystalline counterparts).
Some Amorphous Solar Panels also come with shade-resistant technology or multiple circuits within the cells, so that if an entire row of cells is subject to complete shading, the circuit won't be completely broken and some output can still be gained. This is especially useful when installing solar panels on a boat.
The development process of Amorphous Silicon solar panels also renders them much less susceptible to breakage during transport or installation. This can help reduce the risk of damaging your significant investment in a photovoltaic system.

Here is a stunning video on the revolutionary new solar cell technology. However hard to believe, the new technology amazed us with the ultra thin solar cell which works like a tape for easy installation and reduced material cost. Be bewildered by this new invention which will ultimately change your stereo-type of the appearance of a solar cell.
