Defect
studies
Fundamental studies performed by the group leaded by Professor Jüri Krustok were concentrated mainly on studies of chalcopyrite and kesterite solar cell absorber materials like CuInSe2, CuInS2, CdTe, Cu2ZnSnS4, Cu2ZnSnSe4. Photoluminescence, Raman spectroscopy, photoreflectance, admittance spectroscopy, XPS are the main tools for these studies.

Additionally
we have high scientific competence in science and technology
of different compound semiconductors, including Cu2ZnSnS4,
SnS, Sb2Se3, CuInSe2, CuInS2, CuGaSe2, CdS, CdTe and other
materials. The laboratory of the department is equipped to the
European level: all main scientific and technological
apparatus are not older than 4 years. Our activities are
related to materials research and to solar cell design and
research. Materials research is mainly related
to defect studies in solar cell materials. We are using
photoluminescence in these studies. Our optical system
includes Raman spectrometer (Horiba Jobin Yvon LabRam
HR800),closed-cycle He cryostat (T=8-320K), He-Cd and
semiconductor lasers, computer controlled grating
monochromator and several emission detectors. Our lab has also
lot of technological equipment to build solar cells (electron
beam evaporation system for metals, RF sputtering system for
ZnO, chemical bath technology for buffer layers, high
temperature furnaces) and equipment for chemical analysis,
including EDX, FTIR.
