Silicon Thin Film

A silicon thin film cell uses amorphous (a-Si or a-Si:H) or micro-crystalline (µc-Si or µc-Si:H) silicon. Silicon layer systems are commonly generated by chemical vapor deposition, typically plasma-enhanced (PECVD), with Silane and Hydrogen gas as source materials. The Silicon is deposited on glass, plastic or metal which has been pre-coated with a layer of transparent conducting oxide (TCO).


Amorphous silicon

Amorphous silicon (a-Si) is the non-crystalline form of silicon. It can be deposited in thin films at low temperatures onto a variety of substrates, offering some unique capabilities.


a-Si/µc-Si Silicon (tandem cells)

Tandem silicon module technology combines amorphous Silicon in a top cell and microcrystalline Silicon in a bottom photovoltaic cell for achieving improved cell performances.

 

Front- and back contact

Front and back contact layers extract the electric energy out of the light absorbing layers to be utilized.

Leybold Optics started as early as 2005 being one of the pioneers in industrial production equipment for thin film Silicon tandem cells showing an impressive track record for innovation and production processes.


Deposition equipment for this application:

• Phoebus PECVD system
• Vertical and horizontal inline sputter systems

With these machine platforms, Leybold Optics covers all vacuum process steps in the production chain of amorphous and tandem silicon cells.
