Roadmap on commercialization of metal halide perovskite photovoltaics

Perovskite solar cells (PSCs) represent one of the most promising emerging photovoltaic technologies due to their high power conversion efficiency. However, despite the huge progress made not only in terms of the efficiency achieved, but also fundamental understanding of the relevant physics of the devices and issues which affect their efficiency and stability, there are still unresolved problems and obstacles on the path toward commercialization of this promising technology. In this roadmap, we aim to provide a concise and up to date summary of outstanding issues and challenges, and the progress made toward addressing these issues. While the format of this article is not meant to be a comprehensive review of the topic, it provides a collection of the viewpoints of the experts in the field, which covers a broad range of topics related to PSC commercialization, including those relevant for manufacturing (scaling up, different types of devices), operation and stability (various factors), and environmental issues (in particular the use of lead). We hope that the article will provide a useful resource for researchers in the field and that it will facilitate discussions and move forward toward addressing the outstanding challenges in this fast-developing field

Patterning of gold nanoparticle rings by manipulation of wetting coverage

This report presents a simple, large scale and low-cost alternative approach to fabricate gold nanoparticle (Au NP) ring arrays on Si substrate by using hexagonal close packed (HCP) polystyrene (PS) monolayer as a template and manipulating chemical wetting coverage. With no involvement of sophisticated equipment, Au NP ring structures of tunable sizes and wall thickness are generated. In addition, a qualitative threshold model that well describes the profile of effective packing density of templating molecules is established. Within the framework of the model, the geometric parameters of the ring arrays prepared from this pure chemical approach, the effects of wetting order as well as the selection of surface modifying chemicals are discussed. As the proposed approach takes advantage of chemical wetting difference to specifically modify the substrate surface, it is reasonable to conclude that the shape, size and wall thickness of the Au NP ring arrays are tunable by varying the templating objects and the chemicals used for surface modification, implying potential application in sensing and spectroscopy by engineering ring arrays on demand.Bachelor of Engineering (Materials Engineering

Effects of ethanol and three-phase contact angle on gold nanoparticle adsorption at water/toluene interface

This work investigates the effects of ethanol and the 3-phase (charged Au surface, water/ethanol solution and toluene phase) contact angle on the formation of gold nanoparticle monolayer at water/toluene interface. Although thermodynamic calculation indicates that nanoparticles can be spontaneously adsorbed to the water/oil or water/air interface even without ethanol addition, a large sorption barrier was proposed to hinder the nanoparticle adsorption for the water/air interface. By replacing the air phase with an oil phase (toluene), the sorption barrier was proposed to be reduced to a large extent due to the enhancement in attractive hydrophobic interaction. Besides, ethanol addition was proposed to enhance the nanoparticle adsorption by reducing the repulsive electrostatic interaction. Meanwhile, it was found that the 3-phase contact angle can be adjusted to approach 90 by modulating the ethanol dosage. The effect of ethanol dosage has also been investigated based on the morphology of the monolayer film
