Abstract [en]
This licentiate thesis gives a summary of electrical characterisation techniques, detailing their use to investigate and understand stability and meta-stability in thin-film solar cells, with a focus on the chalcopyrite material system. Experimental data is used to illustrate the information that can be extracted with these measurements, highlighting the deeper insights that can be drawn from complementary measurements. For example, short-circuit current losses in (Ag,Cu)(In,Ga)Se2 after prolonged storage and annealing are attributed to changes in the net doping, as are significant open-circuit voltage losses observed after lightsoaking. Characterisation is also shown to suggest that the amount of Ag in the alloy plays a significant role in its stability, with a similar significance indicated for Ga.
