Solution processed fullerene (C60) films as the electron transport layers (ETLs) promise to substantially reduce the cost of the perovskite solar cells (PSCs). However, the self-aggregation nature of C60 when dissolved in a solvent with high solubility (e.g., o-dichlorobenzene, o-DCB) makes the...

Surface passivation is a promising technique to improve the power conversion efficiency (PCE) and stability of perovskite solar cells (PSCs). Upper surface passivation has been widely used to passivate surface traps which are responsible for interfacial recombination loss. The bottom surface (or...

Oxygen evolution reaction (OER) is one of the important anodic reactions in most of widely used electrochemical conversion devices . However, the four-electron transfer process in OER makes the reaction sluggish and reduces the efficiency accordingly. Although a lot of OER electrocatalysts have...

The paper explores options for a 2050 carbon free energy future for India. Onshore wind and solar sources are projected as the dominant primary contributions to this objective. The analysis envisages an important role for so-called green hydrogen produced by electrolysis fueled by these carbon...

Cloud computing has been recognized as a critical driver of Information-Technology (IT) enabled innovations. In this paper, we review recent cloud computing research from an Operations Management (OM) perspective, by focusing on major operations challenges faced by a cloud provider in three...

In recent years, there has been an increasing trend in supply chains to employ a “control tower” approach to improve supply chain performance. Such a strategy includes vendor- or supplier-managed-inventory (VMI or SMI) where the supplier takes over the control tower, and the other strategy...

This paper is concerned with a delayed fear-effect predator-prey system with diffusion under homogeneous Neumann boundary conditions. To analyze the impact of diffusion on the spatiotemporal dynamics, we first study the predator-prey system without time delay, in which the conditions for local...

When only short-term loans are available, innovative firms may become more reluctant to invest in long-term and highly risky investment projects (i.e., radical innovation). By exploiting the unique situation in China that patenting firms for the first time obtained patent-backed loans (PBLs),...

This comment revisits the analysis in Christensen and Timmins (2022). We identify two critical errors used in the original analysis, one with the data and the other with coding. When either error is corrected several major results in the paper change, either in statistical significance or in...

We thank the authors of this report for their careful re-analysis of our paper, "Sorting or Steering: The Effects of Housing Discrimination on Neighborhood Choice" and the Institute for Replication for supporting this work. In the process of replicating the re- sults published in Christensen and...
