Selenium antimony sulfide (Sb2(S,Se)3) is an attractive photovoltaic absorber material owing to its suitable band gap, large absorption coefficient, and photoelectric properties. Chemical bath–deposited cadmium sulfide (CBD-CdS) is the most widely used buffer layer material for Sb2(S,Se)3...

Ultrathin CdS nanosheets (NSs) are intriguing in photocatalytic hydrogen evolution. Severe photo-corrosion and low visible light utilization, however, impair their applications. To solve this problem, a novel step-scheme (S-scheme) 2D CdS/W18O49 van der Waals (vdW) heterostructure with strong...

Manipulation of the co-catalyst plays an important role in charge separation and reactant activation to enhance the activity of CdS based photocatalysts. Transition-metal phosphides have aroused widespread interest in catalysis owing to their special structure and catalytic behavior. Herein,...

In this paper, we use the copula model so as to compute the Optimal Hedge Ratio. Hedging with OTC markets is probably the most common way of managing risk, and much research has been done within this field. Our investigation contributes to the current literature insofar as we aim to hedge Credit...

We use data on granular holdings of debt and Credit Default Swaps (CDS) referencing non-financial corporations across financial investors, to investigate how CDS reallocate credit risk and whether this increases investor-level riskiness. To guide our investigation, we propose a methodology to...

We examine the effect of firms’ carbon risk management practices on their credit risk. Using difference-in-differences analysis based on two quasi exogenous events involving the 2015 Paris Climate Agreement and the staggered implementation of US state climate adaptation plans, we find that...
