I prepared the samples to demonstrate them in the PhD students meeting in Drezno. I was going to show the differences in the surface morphology after etching in the solutions with different compositions.
I participated in the training on the photovoltaic modules simulator Quick Sun 820A. This simulator allows the measurement of current-voltage characteristics of the modules with simultaneous temperature compensation. The simulator is equipped with a xenon flash lamp with a pulse duration of 15 ms.
