What Are Solar Film Cells?

Solar vitality and ‘going inexperienced’ are getting lots of attention these days. Many individuals are talking about skinny movie solar cells, also known as solar film. This text offers you a rundown on the various technologies on the market, without getting too deep into the chemistry and physics of how they work.

Photo voltaic movie cells are getting a whole lot of attention as a result of they deal with the most important concern with photo voltaic vitality: cost. The development of this technology has take nice strides in recent years because they are cheaper to manufacture than conventional solar panels. Skinny movie photo voltaic panels are what you’ll discover in a photo voltaic calculator, and this technology is being expanded into panels for big residential and industrial use. World Photo voltaic Vitality, for example, just lately installed a 750 kilowatt array that provides 25% of factory’s power needs.

This know-how makes use of the same science that’s found within the rectangular photo voltaic panels we’re seeing more and more of within the world. Instead of using exhausting crystalline silicon that have to be encased in tempered glass and aluminum frames like regular solar panels, the silicon is deposited on a flexible piece of metallic or plastic after which coated. This know-how is usually less efficient, however less expensive to make. To supply the same amount of energy as a standard solar panel, you would wish 30-50% more surface space of skinny film silicon solar.

This technology is less standard than thin movie silicon for a number of reasons. While it’s more cost-effective to fabricate, it is much less efficient than silicon. Moreover, the materials in these cells are typically poisonous, resulting in considerations in regards to the manufacturing process and the long term environmental results of the cells. Studies are being executed as we communicate to investigate the long term toxicity of cadmium telluride since the economics of the technology are very attractive. Typical efficiencies for these cells are around 15%. This means that 15% of the full energy that fell on the cell was converted to electricity.

CIGS is an acronym for’copper indium gallium (di)selenide’ (see why we call it CIGS?). CIGS cells have probably the most promise for bringing down the cost of solar for the reason that economics AND efficiencies are very promising. In 2005, the National REnewable Power Lab achieved a world report 19.9% efficiency for a CIGS cell. This means that 19.9% of the overall vitality that fell on the cell was converted to electricity. This is approaching the world report for a typical photo voltaic panel of 24.7%. This very thrilling as a result of producers anticipate the price of mass-produced thin film cells to be round $1.00/watt. Common silicon solar panels we’re used to seeing are close to $5.00/watt. Companies similar to Shell, Nanosolar, and Honda are investing closely on this technology. Nanosolar is especially fascinating in that is has the backing of Silicon Valley venture capital and the Google founders. They are in the process of building a large manufacturing facility and declare that they are going to produce solar cells at 1/tenth the price of present cells. Very exciting.
