Thin-film solar cells with Cu(In,Ga)Se2 (CIGS) absorber layers have been intensively studied due to their high power conversion efficiencies. CIGS solar cells with Zn(O,S) buffer layers achieved record efficiencies due to their reduced parasitic abso

We demonstrate that based on a post-sulphurization approach the mean sulphur concentration and bandgap of Cu2ZnSn(S,Se)4 (CZTSSe) solar cell absorber layers can be precisely controlled. However, X-ray diffraction and secondary ion mass spectrometry s

Solution-grown Zn(O,S) buffer layers in Cu(In,Ga)Se 2 (CIGS) solar cells are investigated by angle-resolved electroreflectance (ER) spectroscopy. We demonstrate that ER can be used directly to measure the bandgap energy of very thin Zn(O,S) buffer la

Post-deposition treatment (PDT) of the absorber layer with alkali fluorides has led to a significant increase in the efficiency of Cu(In,Ga)Se2 (CIGS) thin-film solar cells. In this contribution, we investigate the influence of alkali PDTs on the abs

Electroreflectance (ER) spectroscopy is utilized to study Cu(In,Ga)Se 2 solar cells with solution-grown CdS and Zn(O,S) buffer layers. Due to the weak ER signals of the thin buffer layers, interference effects can have a strong influence on the ER sp

Currently, the use of Zn(O,S) as buffer material for Cu(In,Ga) Se 2 (CIGS) solar cells is intensely studied in order to further boost the performance of these devices. In this context, nondestructive analytical tools are needed that enable the determ
