The field of organic photovoltaics has developed rapidly over the last 2 decades, and small
solar cells with power conversion efficiencies of 13% have been demonstrated. Light …

Our knowledge of the brain has evolved over millennia in philosophical, experimental and
theoretical phases. We suggest that the next phase is simulation neuroscience. The main …

The focused ion beam (FIB) is a powerful tool for fabrication, modification, and
characterization of materials down to the nanoscale. Starting with the gallium FIB, which was …

Control over the morphology of the active layer of bulk heterojunction (BHJ) organic solar
cells is paramount to achieve high-efficiency devices. However, no method currently …

We synthesized a donor polymer of bis (2-ethylhexyl) thiophene-substituted
benzodithiophene (BDT-Th) and 1, 3-bis (2-ethylhexyl)-5, 7-di (thiophene-2-yl) benzo [1, 2-c …

The helium ion microscope (HIM) has emerged as an instrument of choice for patterning,
imaging and, more recently, analytics at the nanoscale. Here, we review secondary electron …

The efficiency of organic solar cells with donor polymers and non-fullerene acceptors
depends on a complex morphology. Similar chemical and electronic structures impede …

This paper is a review on the combination between Helium Ion Microscopy (HIM) and
Secondary Ion Mass Spectrometry (SIMS), which is a recently developed technique that is of …

Suppressing charge recombination is key for organic solar cells to become commercial
reality. However, there is still no conclusive picture of how recombination losses are …

Powder materials are used in all corners of materials science, from additive manufacturing to
energy storage. Scanning electron microscopy (SEM) has developed to meet morphological …
