In the world of tomographic imaging, atom probe tomography (APT) occupies the high-
spatial-resolution end of the spectrum. It is highly complementary to electron tomography …

Abstract Cu (In, Ga) Se2 thin‐film solar cells have attracted significant research interest in
recent decades due to their high efficiency in converting solar energy into electricity for …

The published external quantum efficiency data of the world-record CdTe solar cell suggests
that the device uses bandgap engineering, most likely with a CdTe x Se1− x alloy layer to …

Abstract Introducing K into Cu (In, Ga)(Se, S) 2 (CIGS) absorbers has led to recent world
record power conversion efficiencies for thin film polycrystalline solar cells. In this work, the …

Back contacts can significantly limit CdTe solar cell performance, reducing both open circuit
voltage (V oc) and fill factor (FF). Copper is an essential component of effective back …

One of the key materials for all-solid-state batteries based on oxide electrolytes is the
polycrystalline Li 7 La 3 Zr 2 O 12 (LLZO). It has been reported that metallic Li can …

The present review gives an overview of the various reports on properties of line and planar
defects in Cu (In, Ga)(S, Se) 2 thin films for high‐efficiency solar cells. We report results from …

Focused-ion beam lift-out and annular milling is the most common method used for
obtaining site specific specimens for atom probe tomography (APT) experiments and …

Passivation of grain boundaries (GBs) and interfaces to suppress recombination and to
improve minority carrier lifetime (MCLT) is essential for the functionality of devices based on …

We use atom probe tomography (APT) for resolving nanometer scale compositional
fluctuations in Cu 2 ZnSnSe 4 (CZTSe) thin-films prepared by co-evaporation and post …
