Semiconducting nanomaterials synthesized using solution methods have played important roles in a wide variety of electronic and optical applications, such as solar cells (SCs), light emitting diodes (LEDs), photodetectors, and sensors. The frontiers in synthesis include new compounds, reducing the size of nanomaterials, increasing the crystallinity of nanocrystals, alternative green synthesis methods to reduce waste and energy, and surface functionalization and characterization. Furthermore, great challenges are encountered in processing nanomaterials from suspensions to uniform thin films on different substrates for optoelectronic device applications. While many publications focus on synthesis and applications of solution-based nanomaterials, issues related to processing, e.g., solvent choice, surface compositions and ligands, and deposition methods, are addressed infrequently. This Special Issue solicits submissions on processing of solution-based semiconducting nanomaterials in addition to their synthesis and applications.

Title: Stereocomplex Crystallization of Polylactide Prompted by One-Dimensional Nanofillers Studied by Molecular Simulations
Author: Yijing Nie
Affiliation: Jiangsu University，[email protected]
Abstract: Dynamic Monte Carlo simulations were performed to investigate the stereocomplex crystallization of polylactide promoted by one-dimensional nanofillers. The presence of the nanofillers can effectively facilitate the formation of stereocomplex crystallites in poly(l-lactide)/poly(d-lactide) blend. The increase of the content of the nanofillers can further lead to the increase in the fraction of stereocomplex crystallites. The enhancement in the stereocomplex formation can be attributed to the heterogeneous nucleation of polylactide chains on the filler surface. The nanofillers can absorb both poly(l-lactide) and poly(d-lactide) chains under the effect of interfacial interactions. In the interfacial regions the blend has better miscibility, and thus stereocomplex crystallites are easier to form during heterogeneous nucleation.
Title: Enhanced Moisture and Thermal Stability in Perovskite Solar Cells Spray-Coated with Polystyrene

Abstract: The major challenge for the future commercialization of hybrid perovskite solar cells (PSCs) is that the device stability is not competitive with the benchmark silicon technology. In this study, we show PSCs with dramatically improved stability deriving from efficient water and moisture screening by using a solution-processed, fast, and cheap technique. Both mixed-cation, mixed-halide [(CH(NH2)2PbI3)0.85(CH3NH3PbBr3)0.15] and pure (CH3NH3PbI3) perovskite solar cells showed remarkable stability towards water and moisture when spray-coated with a polystyrene film. The spray-coated devices retain ∼90% of their original efficiency after 20 hours in water while the devices without protection fully degraded within 10 minutes. Furthermore, polystyrene-coated perovskite films heated overnight up to 95 oC display exceptional thermal resistance, while pure perovskite devices show a significantly increased light stability.
