Photovoltaics

Given the finite nature of fossil fuel resources and the greenhouse gas (CO2) produced when they are used, a fundamental change in power generation in the near future is essential. Regenerative energies such as solar are inexhaustible and ecologically sound.

Photovoltaics uses the photo effect by generating electricity from the energy of sunlights´ photons. PVA TePla offers leading crystal growing technology  for high quality crystals  from which solar wafer are produced.

Crystal Growing Systems

	Typ EKZ 3500 The EKZ 3500/200 is used to produce crystals up to 200mm in diameter. The typical batch weights range between 120 and 150kg, depending on the hot zone installed and the use of feeder for increasing the batch weight. The crystal lengths obtainable from such batch sizes measure about 1.5m in the cylindrical portion.... more

	Typ EKZ 2700 These equipments combine proven mechanical elements with innovative elements for process control. The two plant types differ primarily in the design of crystal drive unit (shaft/cable) and are used for the production of crystals with up to 6” diameter. The dimension of these furnaces allow ... more

	Multi Crystalizer   Vacuum furnace designed for directional solidification (based on Vertical-Gradient-Freeze Process) of multi-crystalline solar silicon ingots for photovoltaic wafer production ... more

	Typ FZ 14 This machine is an intelligently designed piece of equipment, which in addition to meet the requirements in silicon crystal growing at diameters up to 4 inch and at the same time with reasonable physical dimensions. The machine have a crystal growing length of 1300 mm and produces 3" crystals up to ... more

	Typ FZ 14 M For analytical purposes, the FZ-14M has been developed. This a is a floatzone Silicon crystal grower specifically designed in accordance with the requirements of ASTM Std. F1723-96. The FZ-14M converts minature rods of polycrystalline silicon into monocrystalline silicon for use in the assessment of the ... more

	Typ FZ 30 The FZ-30 consists of a main, upper and lower chamber and an upper and lower pulling arrangement, all built as modules. The FZ-30 is fully equipped with access doors, a tank circuit, a control panel, a high frequency generator, a data logging system and an operator’s platform ... more

	Typ SR 110 This machine is very effective since two slim rods are produced at the same time, using a double hole HF-coil connected to one generator. Every care has been taken to make the machine very operator friendly and to allow fast restart of pulling after harvest of the produced slimrods ... more
