Thin Film Photovoltaic

Installing clean, reliable, inflation-proof solar power is easier than ever, thanks to the invention of thin-film photovoltaic (PV) laminates that can be bonded directly onto metal roofing panels. Unlike crystalline PV material, there’s no need for obtrusive racks and heavy, expensive glass. Instead, unbreakable thin-film PV is produced using amorphous silicon, encapsulated in Teflon and other polymers.[kml_flashembed movie="http://www.youtube.com/v/YYJe12X6T50" width="425" height="350" wmode="transparent" /]

Nanosolar

This is a company that as the potential to change the world. It has developed proprietary technology that makes it possible to simply roll-print solar cells that require only 1/100th as thick an absorber as a silicon-wafer cell (yet deliver similar performance and durability). It has so far raised over $1Bn US and is building a factory in the US, Germany and Wales. Their technology dramatically lowers the process cost and complexity involved in the production of thin-film solar cells and makes it possible to scale production very rapidly. The result sets the standard for the technology and products that make it possible to put A Solar Panel on Every Buildingâ„¢. Nanosolar is on track to make solar electricity:

  1. cost-efficient for ubiquitous deployment
  2. mass-produced on a global scale
  3. available in many versatile forms.

From Wikipedia, the free encyclopedia

Thin films are thin material layers ranging from fractions of a nanometre to several micrometres in thickness. Electronic semiconductor devices and optical coatings are the main applications benefiting from thin film construction. Some work is being done with ferromagnetic thin films as well for use as computer memory.

Ceramic thin films are also in wide use. The relatively high hardness and inertness of ceramic materials make this type of thin coating of interest for protection of substrate materials against corrosion, oxidation and wear. In particular, the use of such coatings on cutting tools may extend the life of these items by several orders of magnitude.

Thin-film technologies are also being developed as a means of substantially reducing the cost of photovoltaic (PV) systems. The rationale for this is that thin-film modules are expected to be cheaper to manufacture owing to their reduced material costs, energy costs, handling costs and capital costs. However, thin films have had to be developed using new semiconductor materials, including amorphous silicon, copper indium diselenide, cadmium telluride and film crystalline silicon. In all cases, these technologies face major technical and financial hurdles.

The engineering of thin films is complicated by the fact that their physics is in some cases not well understood. In particular, the problem of dewetting may be hard to solve, as there is ongoing debate and research into some processes by which this may occur.
