“…are the main reasons for considering it as a very much suitable light absorber layer. [5][6][7][8][9][10][11][12][13] The basic structure of a PSC mainly consists of three different layers which are the electron transport layer (ETL), PSK light absorbing layer and hole transport layer (HTL). The PSK layer absorbs light and generates electrons and holes which are extracted and transported to the electrodes by ETL and HTL, respectively.…”

Organo-metal halide perovskite solar cells (PSCs) have received a lot of attention to the photovoltaic research community, mainly due to the rapid development of their cell performances. But industry-level production of PSCs is hindered for several reasons. At present, the use of high-temperature processed electron transport layer (ETL) such as TIO2, the use of chemically unstable ETL such as ZnO and SnO2, etc. are ETL-related obstacles behind this industrialization. Aiming to remove these problems, cerium oxide (CeO x ), one of the most Earth-rich metal oxides has been chosen as ETL for this study. In this study, the SCAPS-1D simulation package has been used for an intensive study on ETL/PSK interface for a methylammonium lead iodide (MAPbI3)-based PSC having CeO x as ETL. From this simulation, the effect of conduction band offset (CBO) between CeO x and MAPbI3 has been found as the key player behind the cell performances. Defects at this interface have also been introduced and varied for studying their effects on cell performance at different CBO values. The temperature stability of a PSC is another important issue that has been considered in this study to find the effect of operating temperature on the PSC. This study would enlighten the researchers in implying some fantastic techniques at the ETL/PSK interface for improving the cell performance that will forward the research community a few steps to use CeO x as a promising ETL in PSC.

Metal oxide thin films have been of prime interest among electrochromic materials because of their chemical stability, strong adherence to various substrates, and high coloration efficiency. Compared to other transition metal oxides, such as V2O5, MoO3, and TiO2, tungsten oxide (WO3) exhibits superior electrochromic properties, including long‐term durability and excellent contrast ratio. High‐power impulse magnetron sputtering (HiPIMS) holds great potential in fabricating durable WO3‐based electrochromic layers. However, the tungsten target‐plasma interactions in reactive‐HiPIMS deposition of WO3 and their role in modulating the electrochromic function of the resulting WO3 coatings are yet to be understood. Here, we provide evidence that by controlling the HiPIMS pulse length, the stoichiometry of tungsten oxide structures can be tuned to optimize the transparency and electrochromic function of the coatings. X‐ray photoelectron spectroscopy (XPS) data showed that at pulse lengths shorter than 85 μs, the concentration of suboxide compounds is less than that of tungsten trioxide, while for pulse lengths longer than 100 μs, this balance is reversed. The average optical transparency of the coatings in the range of visible light was higher than 80%. The optical transmittance modulation (ΔT) of 38.1, 36.2 and 34.3% and coloration efficiency of 41.3, 38.4, and 35.9 cm2 C−1 were measured for the WOx samples deposited at pulse lengths of 70, 85 and 100 μs, respectively. Tuning the HiPIMS pulse characteristics is a simple strategy to deposit tungsten oxide films with tuned electrochromic properties for an array of applications, from smart windows to wearable displays.This article is protected by copyright.
