We report that UV-ozone treatment of TiO2 anatase thin films is an efficient method to increase the conductance through film by more than 2 orders magnitude. The in quantified via conductive scanning force microscopy on freshly annealed and UV-ozone-treated fluorine-doped tin oxide substrates. increased results a 2% average power conversion efficiency (PCE) methylammonium lead iodide-based perovskite solar cells. PCE values up 19.5% for mesoporous cells are realized. additional reduced...
In this study we investigate the influence of operation method in Kelvin probe force microscopy (KPFM) on measured potential distribution. KPFM is widely used to map nanoscale distribution operating devices, e.g., thin film transistors or cross sections functional solar cells. Quantitative surface measurements are crucial for understanding principles nanostructures these electronic devices. Nevertheless, prone certain imaging artifacts, such as crosstalk from topography stray electric...
Abstract Members of the phage shock protein A (PspA) family, including inner membrane-associated 30 kDa (IM30), are suggested to stabilize stressed cellular membranes. Furthermore, IM30 is essential in thylakoid membrane-containing chloroplasts and cyanobacteria, where it involved membrane biogenesis and/or remodeling. While well known that PspA bind membranes, mechanism stabilization still enigmatic. Here we report ring-shaped super-complexes disassemble on resulting formation a...
In organic electronics, local crystalline order is of critical importance for the charge transport. Grain boundaries between molecularly ordered domains are generally known to hamper or completely suppress transfer and detailed knowledge electronic nature future minimization such malicious defects. However, grain typically hidden within bulk film consequently escape observation investigation. Here, a minimal model system in form monolayer-thin films with sub-nm roughness prototypical n-type...

ABSTRACT The inner membrane-associated protein of 30 kDa (IM30) is essential in chloroplasts and cyanobacteria. spatio-temporal cellular localization the appears to be highly dynamic triggered by internal as well external stimuli, mainly light intensity. A soluble fraction localized cyanobacterial cytoplasm or chloroplast stroma, respectively. Additionally, attaches thylakoid membrane envelope cytoplasmic membrane, respectively, especially under conditions stress. IM30 involved biogenesis...
