Co-evaporation of NaF during the 3rd stage of the low temperature Cu(In,Ga)Se2 multi-stage process is compared to post-deposition treatment (PDT) with NaF in view of their influence on the electronic and structural properties. In case of NaF co-evapo

In thin-film Cu(In,Ga)Se2 (CIGS) solar cells a large number of intrinsic defect types are possible in the chalcopyrite structure and can influence the efficiency of the solar cell. Defect characterization is therefore essential. In this study Deep Le

The introduction of a KF postdeposition treatment (KF PDT) of Cu(InGa)Se2 (CIGS) thin films has led to the achievement of several consecutive new world record efficiencies up to 21.7 for the CIGS solar cell technology. The beneficial effect of the KF

Active electronic implants are powered by primary batteries, which induces the necessity of implant replacement after battery depletion. This causes repeated interventions in a patients’ life, which bears the risk of complications and is costly. By
