Figure 1 :  The mini solar module after scribing.   The laser scribing, which means digging lines within the layers of the solar cells, is a significant process within the fabrication scheme for solar cells modules. Scribing is done in order to contact the cells within the module, upscale the area of ​​these manufactured modules for industrial applications and save the efficiency in the meantime. My project is concerned with the scribing of the absorber material layer of CIGS thin film solar cells. This involves optimization of the parameters of the lasers beams, pico and nanosecond ones , and comparing, qualitatively and quantitatively,Read More →

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 timeRead More →
