Abstract

Background: Long-term effects of outdoor and indoor air pollution on chronic liver disease (CLD) remain unclear. Thus, the study was conducted to investigate the relationship between prolonged exposure to ambient particulate matter (PM1, PM2.5 and PM10) and household fuel usage with CLD. Methods: Data from the China Health and Retirement Longitudinal Study (CHARLS) covering the years 2011 to 2020 were employed. In the cross-sectional analysis, 16,680 participants were included, while 12,969 participants were enrolled in the longitudinal study. The associations between various sizes of particulate matter and CLD were elucidated using logistic regression model and generalized linear-mixed models. Additionally, the additive effects of ambient particulate matter (PM) levels and the utilization of solid fuels for cooking were investigated, with a comparison of effect sizes between converted and non-converted fuel types. Results: Over a 10-year follow-up period, 746 (5.75 %) individuals developed CLD. For a 1-year average concentrations, PM1, PM2.5 and PM10 were each linked to a 1.549 (95 %CI:1.522–1.576), 1.296 (95 %CI:1.276–1.317) and 1.134 (95 %CI:1.118–1.150) fold risk of incident CLD per 10 μg/m3 increase, respectively. A similar effect of PM concentrations over a 2-year period on CLD was observed. Moreover, simultaneous exposure to ambient PM and solid fuels is associated with an increased risk of CLD. Those who continue using solid fuels may face a higher risk of CLD compared to individuals who switch to cleaner cooking fuels. Female participants, smokers, and individuals with shorter sleep duration and multiple chronic diseases exhibited slightly stronger effects. Conclusion: Long-term exposure to various sizes of PM (PM1, PM2.5, PM10) has been linked to an elevated risk of CLD incidence. Co-exposure to ambient PM and solid fuels is associated with higher health risks.

Abstract

Abstract Self‐assembled monolayers (SAMs) employed in inverted perovskite solar cells (PSCs) have achieved groundbreaking progress in device efficiency and stability for both single‐junction and tandem configurations, owing to their distinctive and versatile ability to manipulate chemical and physical interface properties. In this regard, we present a comprehensive review of recent research advancements concerning SAMs in inverted perovskite single‐junction and tandem solar cells, where the prevailing challenges and future development prospects in the applications of SAMs are emphasized. We thoroughly examine the mechanistic roles of diverse SAMs in energy‐level regulation, interface modification, defect passivation, and charge transportation. This is achieved by understanding how interfacial molecular interactions can be finely tuned to mitigate charge recombination losses in inverted PSCs. Through this comprehensive review, we aim to provide valuable insights and references for further investigation and utilization of SAMs in inverted perovskite single‐junction and tandem solar cells.

Abstract

Perovskite solar cells (PSCs) have been very popular in the field of photovoltaics. In inverted PSC structures, the hole transport layer deposited before the perovskite photoactive layer plays a crucial role in the power conversion efficiencies (PCEs) and ambient stability of the device. Here, we developed a facile method of preparing NiO hole transport layers with the aid of polymethyl methacrylate (PMMA) for inverted perovskite solar cells. Compared with reported fabrication methods, this route has the advantages of simple, low temperature, and low-cost processing. The corresponding devices exhibited a champion power conversion efficiency (PCE) of 17.78% and good stability. Various characterization experiments, XRD, Raman, AFM, SEM, PL studies etc., were carried out to confirm the superior effect of the NiO film prepared by the new method. We believe that this facile route will be a significant contribution for preparing high performance inverted perovskite solar cells.

Abstract

Perovskite crystal quality plays an important role in perovskite solar cells, given that multiple grain boundaries and trap states in the perovskite films hamper further enhancement of solar cell efficiency. Using the solution method to prepare perovskite films with large grains and high coverage requires further improvements. Herein, we introduce Lewis base urea as an additive into the precursor of perovskite to control the crystallization dynamics, allowing for large-grain crystal growth. As a result, MAPbI3 films with urea as an additive are well crystallized with large crystal grains of sizes >3 μm. The large-grain perovskite is found to simultaneously improve the power-conversion efficiency (PCE) and device stability. With an optimal urea additive of 20 mol%, the PCE is significantly increased from 15.47% for the reference MAPbI3 solar cell to 18.53% for the device with MAPbI3 with urea as an additive. Finally, the optimized device demonstrates excellent stability and maintains 80% of the initial PCE after 60 days.
