Material Advancements in Fabrication of Mixed‐Matrix Membranes

Abstract: The mixed-matrix membrane (MMM) is a new membrane material for gas separation and plays a vital role for the advancement of current membrane-based separation technology. Blending between inorganic fillers like carbon molecular sieves, zeolite, metal oxides, silica and silica nanoparticles, carbon nanotubes, zeolitic imidazolate framework, metal organic framework, and glassy and rubbery polymers etc. is possible. Due to mechanical, thermal, and chemical stability, these membranes achieve high permeability and selectivity as compared to pure polymeric materials. Despite of these advantages, the MMM performances are still below industrial expectations because of membrane defects and related processing problems as well as the nonuniform dispersion of fillers in MMMs. Material selection for organic and inorganic phases, preparation techniques, material advancements, and performance of MMMs are discussed. Issues and challenges faced during MMM synthesis as well as problem solutions are highlighted.

Recent progress in perovskite solar cells

Abstract: Perovskite hybrid solar cells are in vogue in solar cell research. Dye-sensitized solar (DSS) cells, thin film solar cell and silicon solar cell, among others, owing to their efficiencies that are comparable to crystalline Si solar cells and ease of fabrication by a low-temperature solution technique. Although perovskite solar cells have been accounted for to exhibit enhanced output of about 21% from about 9.7%, limited researches have been conducted to find out their low stability that impedes outdoor applications. The issue of degradation of perovskite and the stability of perovskite solar cells should be addressed for good reproducibility and long life time with high conversion efficiencies. The present review aims to represent an account of the advancement in the organic, inorganic perovskite solar cells and the extent of fabrication techniques with a view to understand the material efficiency relationships.
