Thin Film Efficiency Solar Panel

Thin film solar cells are commercially used in several technologies including cadmium telluride cdte copper indium gallium diselenide cigs and amorphous thin film silicon a si tf si.

Thin film efficiency solar panel.

A thin film solar cell is a second generation solar cell that is made by depositing one or more thin layers or thin film tf of photovoltaic material on a substrate such as glass plastic or metal. Cadmium telluride thin films have a peak recorded efficiency of more than 22 1 percent the percentage of photons hitting the surface of the cell that are transformed into an electric current. Each type of xtreme solar panels has the efficiency range of 10 15 percent which makes them sit among the best thin film solar panels presently in the open market.

They are also less toxic and more durable than cdte and cigs thin panels. Types of thin film solar cells. Commercialized thin film solar panels on the market consist of rare earth elements like indium and gallium or highly toxic metals like cadmium. They are less expensive than the more standard silicon thin film cells.

Unlike most thin film solar technologies cigs solar panels offer a potentially competitive efficiency to traditional silicon panels. Both of these thin film solar panel types have. Thin film solar panels are less durable than crystalline panels so they degrade faster which is why they also come with a shorter warranty. But through the manufacturing process of stacking several layers the efficiency of a si thin film solar panels have higher efficiency rates around 6 8 percent.

Solar thin film companies are coming under siege again due to therelentless fall in the prices of crystalline silicon panels in recentmonths of 2011 note large number of thin film companies went bankruptthe last time polysilicon prices fell off a cliff in the post lehmancrisis period in 2008 end applied material the biggest solar equipment. Best thin film pv brands 1 stion. This type of thin film panel follows cdte panels in popularity. Advantages and disadvantages of cigs solar panels.

With efficiencies exceeding 20 measured in the laboratory there may be a continuing place for high efficiency cigs panels in the general solar panel market. The low efficiency rating means you would need to install more thin film panels to produce the same amount of electricity as a mono or polycrystalline solar panel. Researchers have recently achieved 23 4 efficiency with thin film cell prototypes but thin film panels that are commercially available generally have efficiency in the 10 13 range.
