2Project Summary
- Transparent conductive oxides (TCO) are materials
that exhibit electrical conductivity and high
optical transparency together with a wide
band-gap. The traditional applications of these
materials are flat-panel displays, light-emitting
diodes, solar cells, and imaging sensors. - The aim of this project is the preparation by
low-cost sol-gel methods of improved TCO (ITO,
ZnO) and of new generation of TCO (Nb or V doped
TiO2, SrCu2O2) n and p type films with various
morphologies on different substrates (silicon,
glass and plastics), having a very stable
surface. - A complete optical and microstructural
characterization of the TCO samples will be
performed by ellipsometry in a wide spectral
range, from UV to Mid-IR (our IR ellipsometer
being the only one available in Romania) and the
results will be corroborated with those obtained
by complementary methods (UV-VIS, IR and Raman
spectroscopy, XRD, XPS, AFM, SEM, TEM, electrical
measurements). - A database for optical constants of the TCO
investigated materials in the IR range (2-33?m),
which for the moment is lacking in the
literature, will be provided. - In the frame of this project the best films
obtained will be used in specific tests for
solar-cell application.
