“…Surface modification, which can be achieved by etching [24], chemical treatment [25,26], or physical treatment [27,28], provides the opportunities to tune optical, electrical, [29][30][31][32][33][34][35] and interfacial [36-38] material properties. Owing to the availability of reactive groups, mostly soft nucleophiles or electrophiles, most polymer surfaces can be readily modified through chemical grafting by simply exposing the material to an appropriate reagent(s) [1,[7][8][9]14,15,[17][18][19][20][21][22][39][40][41][42][43][44][45][46][47][48][49][50][51][52].…”

Abstract:Modifying the chemistry of a surface has been widely used to influence interfacial properties of a material or nature of interaction between two materials. This article provides an overview on the role of polyfunctional molecules, specifically silanes, in surface modification of polar surfaces (bearing soft nucleophiles). An emphasis on the mechanism of the reaction in the presence of adsorbed water, where the modifying reagents are hydrolysable, is discussed. To highlight the complexity of the reaction, modification of paper with trichlorosilanes is highlighted. Preparation of hydrophobic cellulosic paper, and structure-property relations under different treatment conditions is used to highlight that a monolayer is not always formed during the surface modification. Gel-formation via step-growth polymerization suggests that at the right monomer:adsorbed water ratio, a monolayer will not form but rather self-assembly driven particle formation will occur leading to a textured surface. The review highlights recent work indicating that the focus on monolayer formation, is at the very least, not always the case but gel formation, with concomitant self-assembly, might be the culprit in understanding challenges associated with the use of polyfunctional molecules in surface modification.

“…Recently, organo-uorine 1 compounds have been adopted for surface modication of paper due, in part, to their hydrophobicity and ease of use. [2][3][4][5] Fluorine based reagents, however, can form toxic hydrogen uoride (HF) or hydrouoric acid when mixed with water or upon degradation. 6 HF penetrates the skin and insidiously destroys underlying body tissues.…”

“…Furthermore, the a-SiO:H layer showed less light-induced degradation (LID) effect in comparison to the a-Si:H. In fact, several experimental and simulations studies reveal a difference in the LID of 5.7 % [23]. The effect of (n)a-SiO:H layer on the solar cell performance were investigated using simulation and exprementals method in [22][23][24]. The results show that the wide-bandgap a-SiO:H as an n-doped layer can improve the open-circuit voltage Voc as well as the fill factor.…”

Hydrogeneted amorphous silicon (a-Si:H) based solar cells are promising candidates for future developments in the photovoltaic industry. In fact, amorphous silicon technology offers significant advantages including low cost fabrication and possibility to deposition on flexible substrat as well as low temperature fabrication. Much progress has been made since the first single junction cell in amorphous silicon made in 1976 by Carlson and Wronski. However, the performance of the solar cells based on a-Si:H is limited by the high defect density and degradation induced by exposure to light, or Staebler-Wronski effect. To become competitive, the performance of the solar cells based on a-Si:H must be improved. In order to improve the performance of a-Si:H solar cells, much research is directed to optimization techniques. The improvement in performance is therefore based on the optimization of the different layers of the solar cell, in particular, the window layer and the absorber layer (intrinsic). The aim of this work is to give an overview on the different techniques and strategies that is used to improve the performance of solar cell. This work is therefore focus in three main areas: first, optimization of window layer, in particular, the p/i interface using wide band gap alloys such as a-SiC:H, second development of high quality absorber layer using band gap engineering, and alloys such as a-SiGe:H. last, optimizing n-type layer and i/n interface.
