A constant adjustable force Fs was superimposed to eliminate tube sagging due to large thermal expansion coefficient of polymeric materials at the processing temperature and create axial stress on the polymeric micro tube (Fig. 1).
Due to strain rate influence on the forming behavior of polymeric materials, the test device was designed to enable an adjustable velocity of pressure increase via the piezo valve.
The forming trials of the demonstrator were conducted with two different polymeric materials; PA6 and PET.

Direct band gap benefits the light absorption of CZTS materials because of the high electron transition probability, and this can be seen in the calculated optical properties in the next section.
Absorption coefficient is one of the most important parameters for absorber layer materials in their photovoltaic applications.
Optical conductivity reflects the change of the conductivity of materials arising from illumination.
The two CZTS materials are transparent above the plasma frequency, where most light passes through without being absorbed by the materials, so the properties relevant to light absorption such as , and all approach to zero.
