“…( 6 ) and ( 7 ) describes the recombination process where R Lan and R trap stand for the Langevin bimolecular and trap-assisted monomolecular recombination, respectively 125 , 132 . The recombination of two free opposite charges created from different CTEs refers to Langevin bimolecular, and the recombination of a free charge with an immobilized charge at a trap state refers to monomolecular, where the first is defined as 133 : where C Lan = q ( μ n + μ p )/ ε HM , stands for the recombination coefficient predicted by Langevin model, ξ is an additional reduced factor taking into account experimentally derived reduced Langevin factor 134 – 137 , and n 1 and p 1 are the characteristic electron and hole concentrations, respectively, the product of which is equal to the square of intrinsic carrier density, i.e., n 1 p 1 = n i 2 138 .…”

Numerical-based simulations of plasmonic polymer solar cells (PSCs) incorporating a disordered array of non-uniform sized plasmonic nanoparticles (NPs) impose a prohibitively long-time and complex computational demand. To surmount this limitation, we present a novel semi-analytical modeling, which dramatically reduces computational time and resource consumption and yet is acceptably accurate. For this purpose, the optical modeling of active layer-incorporated plasmonic metal NPs, which is described by a homogenization theory based on a modified Maxwell–Garnett-Mie theory, is inputted in the electrical modeling based on the coupled equations of Poisson, continuity, and drift–diffusion. Besides, our modeling considers the effects of absorption in the non-active layers, interference induced by electrodes, and scattered light escaping from the PSC. The modeling results satisfactorily reproduce a series of experimental data for photovoltaic parameters of plasmonic PSCs, demonstrating the validity of our modeling approach. According to this, we implement the semi-analytical modeling to propose a new high-efficiency plasmonic PSC based on the PM6:Y6 PSC, having the highest reported power conversion efficiency (PCE) to date. The results show that the incorporation of plasmonic NPs into PM6:Y6 active layer leads to the PCE over 18%.

“…Graphene is a material with many special properties such as high thermal and electrical conductivity, very large hardness (hundreds of times higher than steel) and a large specific surface area. Therefore, this material has been strongly researched for many important application fields such as energy storage, solar cells, transparent electrodes, catalysts, sensors, composite polymer materials, and environmental treatment [3][4][5][6][7][8][9][10][11][12].…”

We present a novel method of the solution plasma exfoliated techniques for the production of graphene sheets from recycled battery core at room temperature. This is a fast, simple and efficient method to produce graphene sheets using electrode pairs with DC high voltage power sources which were immersed in a solution. The as-prepared samples were characterized by various techniques such as scanning electron microscopy (SEM), atomic force microscopy (AFM), Raman scattering, and optical emission spectroscopy (OES). The obtained results showed that graphene has an average diameter of 1.5 m and a thickness of about 3 nm in respect of 7 to 10 layers. The prepared graphene was used as an effective adsorbent for the removal of methylene blue (MB) and Rhodamine B (RhB) from aqueous solutions. As a result, the adsorption efficiency of MB and RhB was determined to be 91% and 87 %, respectively. This is an attractive method to replace the previously reported graphene synthesis method.

“…Graphene, a flat monolayer of carbon atoms that are packed into 2-D honeycomb lattices, has attracted considerable attention in recent years for its high thermal and electrical conductivity, outstanding mechanical strength, and large specific surface area. Graphene-based materials have the potential for application to several fields, such as energy storage [ 1 , 2 ], transparent electrodes [ 3 ], lithium-ion batteries (LIBs) [ 4 , 5 , 6 , 7 ], solar cells [ 8 ], fuel cells [ 9 , 10 ], air separation [ 11 ], and building materials [ 12 ]. Therefore, there is a need for high-quality, large-scale graphene samples.…”

A simple, novel approach is proposed for the preparation of plasma-exfoliated graphene (PEGN) by reducing graphene oxide (GO) through a dielectric-barrier discharge (DBD) plasma treatment in a H2 atmosphere. The surface chemistry, microstructures, and crystallinity of the prepared samples were characterized via X-ray photoelectron spectroscopy, transmission electron microscopy, and Raman spectrometry to determine the formation mechanism of the PEGN. The results demonstrated that the prepared PEGN had only a few layers in its structure and that most of the functional groups containing oxygen on the GO surface were removed. The PEGN exhibited a considerably higher capacity, better cycling stability, and favorable electron transfer rate for use as a cathode material for lithium-ion batteries. This proposed approach is fast, convenient, and inexpensive, constituting a novel means of producing graphene.
