TL;DR: Piezoforce microscopy is used to show unambiguously, for the first time, the presence of ferroelectric domains in high-quality β-CH3NH3PbI3 perovskite thin films that have been synthesized using a new solution-processing method.

TL;DR: Using photoconductive atomic force microscopy spectroscopy to map for the first time variations of PV performance at the nanoscale for planar PSCs based on hole-transport-layer free methylammonium lead triiodide thin films reveals substantial variations in the photoresponse that correlate with thin-film microstructural features.

TL;DR: Luria et al. as discussed by the authors used 3D imaging of current pathways in a working CdTe solar cell with nanoscale resolution and observed electrically active defects, which contribute to conduction.

TL;DR: In this paper, a grafting-through brush polymerization mechanism was proposed to avoid the growth of very long chains while promoting the growth in shorter chains by reversing the monomer concentration gradient found in the commonly used grafting from technique, where monomer concentrations are lowest at the substrate and highest in the surrounding solution.

TL;DR: In this article, photo-conductive AFM spectroscopy (pcAFMs) is proposed as a high-resolution approach for investigating nanostructured photovoltaics, uniquely providing nanoscale maps of PV performance parameters such as short circuit current, open circuit voltage, maximum power, or fill factor.
