This study presents a novel, integrated approach to investigating and characterizing the impact of humidity on Insulated-Gate Bipolar Transistors (IGBTs) within large-scale inverter systems. Combining meticulously designed experimental setups and adv

Abstract Carrier-selective and passivating SiO $$_{\rm x}$$ x /TiO $$_{\rm y}$$ y heterocontacts are an attractive alternative to conventional contacts due to their high efficiency potentials combined with relatively simple processing schemes. It is

We examine two different silicon solar cell designs featuring full-area electron-selective contacts based on ultrathin (2–3 nm) titanium oxide (TiOx) films deposited by atomic layer deposition. The first cell design applies a layer stack to the cel

Metastable defects can decisively influence the diode factor and thus the efficiency of a solar cell. The diode factor is also influenced by the doping level and the recombination mechanisms in the solar cell. Here we quantify how the various paramet

To achieve a high fill factor, a small diode factor close to 1 is essential. The optical diode factor determined by photoluminescence is the diode factor from the neutral zone of the solar cell and thus a lower bound for the diode factor. Due to meta

Contacts to crystalline silicon (c-Si) based on ultrathin layers of silicon oxide (SiO y ) and titanium oxide (TiO x ) have recently been shown to be highly selective to electrons if aluminum (Al) is used as top metal. Such SiO y /TiO x /Al electron-

Atomic-layer-deposited titanium oxide (TiOx) is examined for the application as electron-selective full-area contact to n−type silicon solar cells. Although the surface passivation quality of TiOx-...

We characterize the surface passivation properties of ultrathin titanium oxide (TiO x ) films deposited by atomic layer deposition (ALD) on crystalline silicon by means of carrier lifetime measurements. We compare different silicon surface treatments

We characterize the electronic properties of crystalline silicon (c-Si)/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) junctions by means of contactless carrier lifetime measurements. The measurements demonstrate that this type o
