Item Trends in Selected Birth Defects among Parents from Below Poverty Line Population in Karnataka during 2010-2020(Wolters Kluwer Medknow Publications, 2022) Nanjunda, D.C.; Jyothi Lakshmi, S.; Rajesh Acharya, R.H.; Mishra, A.K.The aim of the study is to reveal the common birth defects among parents of newborns belonging to the below poverty line (BPL) category in Karnataka state (South India) by analyzing Suvarna Arogya Suraksha Trust data. In the last 10 years, 3672 kids in BPL families have been born with various birth abnormalities. It is found that 50.3% of newborns have anorectal malformations, 33.1% have hypospadias, 6.0% have diaphragmatic hernia, 5.1% have esophageal atresia, and 2.8% have intestinal atresia and obstruct. As a parent's age rises, the likelihood of having a child with birth abnormalities raise as well, particularly anorectal malformations than diaphragmatic hernia. Male newborns have a higher risk of birth defects. We hypothesized that poverty, material deprivation, and low socioeconomic profile throughout the life course among the BPL community could be some of the key reasons for poor maternal health care and related neonatal outcomes. © 2022 Indian Journal of Public Health | Published by Wolters Kluwer-Medknow.Item Performance analysis of hybrid perovskite solar cells based on different halide ions(Elsevier Ltd, 2025) Jarwal, D.K.; Mishra, A.K.; Dubey, C.; Jangid, A.K.; Bhargava, K.; Kumar, R.; Rawat, G.Here, we have investigated the importance of incorporating different halide ions into perovskite material of the hybrid perovskites-based solar cells (PSCs) and optimized the performance of the PSCs. The n-i-p device structure as FTO/ZnOS/Absorber Material/CuO/Au, is used, where ZnOS and CuO are as electron and hole transport layers, respectively. The CH3NH3PbI3, CH3NH3PbBr3 and CH3NH3PbI3?xClx are exploited as an active absorber layer, with FTO and Au serving as front and back electrodes, respectively. Their performance is studied in terms of various performance parameters viz. Open-circuit voltage (Voc), short circuit current density (Jsc), fill factor (FF), and power conversion efficiency (PCE). Moreover, a systematic optimization and comparison is conducted to examine the influence of perovskite layer thickness, defect density, and operating temperature on the performance of the three modelled PSCs. The results show that CH3NH3PbI3 based hybrid PSC exhibits the highest PCE of 25.34 % at 300 K, at a defect density of 1015cm?3 and absorber layer thickness of 600 nm. The other key parameters include VOC of 1.15 V, JSC of 25.21 mA/cm2 and FF of 86.4 %. The analysis highlights the importance of numerical simulations in predicting the influence of structural variations in perovskite materials on performance of the hybrid perovskite solar cells. © 2025 Elsevier Ltd
