The improvement of a synthesis perovskite materials with using long thermal annealing
Transparent conducting oxides (TCOs) are widely used in optoelectronic applications such as ﬂat panel displays, solar cells and thin-film photovoltaics. Therefore, the rapid increase in the use of TCO materials will continue. Perovskite oxides of the general formula ABO3, such as CaSnO3, have shown their potential as sustainable alternative to conventionally used TCOs.
The main purpose of my project is to synthesise different ABO3 (A=Ba, Ca, Sn; B=Mn, Sn, Ti) materials with an emphasis on the thorough structural characterization of these materials (using X-Ray diffraction, UV-Vis spectrometry) for samples prepared with different time of annealing.
Ideally, we aim to gain a better insight into stable and/or metastable perovskite structures (and the validity of Goldschmidt’s rule under this regime) which may suggest routes to novel TCO materials.
