Smooth and aligned single walled carbon nanotube (SWNT) thin films with improved optoelectronic performance are fabricated using a superacid slide casting method. Deposition of as made SWNT thin film on silicon (Si) together with post treatments result in SWNT/Si hybrid solar cells with unprecedented high fill factor of 73.8%, low ideality factor of 1.08 as well as overall dry cell power conver...
Abstract Superacids are strong acids with an acidity higher than pure sulfuric acid. Recently, superacid treatment of monolayer transition metal dichalcogenide (TMDC) flakes, such as MoS 2 and WS , has shown a dramatic enhancement optical properties, photoluminescence (PL) intensity. The molecule is bis(trifluoromethane)sulfonimide (TFSI). In this review paper, we summarize discuss the recent w...
The reduction of parasitic recombination processes commonly occurring within the silicon crystal and at its surfaces is of primary importance in crystalline silicon devices, particularly in photovoltaics. Here we explore a simple, room temperature treatment, involving a nonaqueous solution of the superacid bis(trifluoromethane)sulfonimide, to temporarily deactivate recombination centers at the ...
The phase behavior of rodlike molecules with polydisperse length and solvent-mediated attraction and repulsion is described by an extension of the Onsager theory for rigid rods. A phenomenological square-well potential is used to model these long-range interactions, and the model is used to compute phase separation and length fractionation as a function of well depth and rod concentration. The ...
Disproportionation reactions of chlorosilane compounds in the presence boron trichloride yield compound H[B(SiCl3)4]. Spectroscopic analyses yellow-whitish solid with IR-, Raman-, and NMR-spectroscopy (29Si, 11B) show a highly symmetric anion containing boron, which is fourfold coordinated silicon. Due to high symmetry 1J(11B,29Si) even 1J (10B, 29Si) couplings can be observed NMR spectra disso...
