Data SheetDownload Icon

Production Effusion Cell PEZ is specially designed to meet the particular requirements for II-VI semiconductors, CIGS and for Kesteride solar cell material deposition.  The operating temperature range is 200-1400°C. It allows evaporation or sublimation of a large number of elements and compounds, including standard materials such as Se, Ga, Cu, In, NaF, Sn or Zn.

Besides standard filaments SF, dual filament DF configurations are available, meeting the differing requirements of the evaporation materials. The figure on the right-hand side shows the cylindrical 160ccm crucible for the PEZ 63-160-60 with the beam shaping insert in the orifice.

The PEZ offers precise flux reproducibility and excellent thickness uniformity.
Very good source material utilization and flux stability are achieved by using of the beam shaping insert. Crucible inserts not only reduce the effect of fill level-related flux shift, but also act as a thermal buffer virtually eliminating shutter transients.

The consequent use of power and TC feedthroughs on separate DN16 CF flanges allows easy servicing. Completely closed power connectors with gold-plated contacts guarantee easy and safe handling of the PEZ.

Filling levels in PBN 160-60

The PEZ design offers wide flexibility to adapt to the particular requirements of UHV deposition applications with high throughput such as  fabrication of II-VI semiconductor devices or thin film solar cell development.

Cylindrical 160 cm³ crucible for the PEZ 63-160-60 with the beam shaping insert in the orifice

Simple removal of crucible and beam shaping insert from top allows easy crucible replacement and source refill. Our proprietary cell encapsulation provides increased lifetime for the heater and the shielding  in the aggressive Se and/or S environment.


The PEZ  is especially suited for II-VI semiconductors, CIGS and for Kesteride solar cell material growth.
It allows evaporation of a large number of elements and compounds, including materials such as Se, Ga, Cu, In, NaF, Sn or Zn. The PEZ provides a robust cell design and the consequent optimization of many details leading to a improvement of stability and reproducibility, as well as excellent reliability and easy servicing.

Capacity for the PEZ 63-160-60: 160 ccm crucible for a 30° tilted cell geometry:

density minimum maximum
copper 8,954 g/cm3 98 g 877 g
indium 7,31 g/cm3 95 g 819 g
gallium 5,904 g/cm3 77 g 661 g

The PEZ 63-160 effusion cell is suitable for fast ramping procedures to comparably high deposition rates. With a precise dynamic ramping, the rate profiles of inline deposition systems can be reproduced. Process development and transfer from MBE-like co-evaporation systems to inline production systems become much easier.

A more detailed description you will find in the attached paper (28th EU-PVSEC, 3BV.5.17).
