TL;DR: In this article, the effect of nano-planarization of pyramidally textured wafer surfaces by wet-chemical treatment on solar cell parameters is investigated, and the obtained significant increase of the photocurrent at long wavelengths is attributed to the improvement of the back side reflectance, whereas the higher fill factor is assigned to a lowering of back contact resistance.

TL;DR: In this article, a series of pulsed EPR measurements in S-, X-, and Q-band were performed to resolve hidden complexity of the EPR spectra of µc-SiC:H and determine the nucleus responsible for the hyperfine pattern observed in previous studies.

TL;DR: In this article, a series of molecular manganese complexes of varying nuclearity and metal oxidation state, formed in Nafion polymer, were shown to effectively catalyze water oxidation under neutral pH conditions with the onset of electrocatalysis occurring at an overpotential of only 150 mV.

TL;DR: Using orientation dependent electrically detected magnetic resonance and g tensor calculations based on density functional theory, microscopic structures are assigned to paramagnetic states involved in spin-dependent recombination at the interface of hydrogenated amorphous silicon crystalline silicon (a-Si:H/c-Si) heterojunction solar cells.
