The lead free intrinsic Ch3NH3SnI3 perovskite is used as absorber material in solar cell along with different ETL and HTL. SCPAS 1D software utilized for modelling analysis of the cell. ETLs are SnO2, TiO2, ZnO, CdS IGZO HTLs Cu2O, CuI, NiO, CuSCN MaSnBr3. investigation revealed that most suitable TiO2 HTL Cu2O. However, we have chosen ZnO proposed owing to its advantage over little observed difference on efficiency. Further has been made analyze impact change thickness defect parameters....
We have analyzed the effect of Ch3Nh3PbI3 interfacial layer on Cu2O/TiO2 based solar cells using SCAPS 1D. The initial investigation has shown that insertion resulted in better efficiency and lesser impact defect variations. Ag/Cu2O/Ch3Nh3PbI3/TiO2/FTO enhanced comparison to Ag/Cu2O/TiO2/FTO cell. Further, we varied thickness density Cu2O it is observed variation relatively less efficiencies optimized obtained 2 µm. electron affinity TiO2 understand its performance cells. Later, defects...
Abstract We have used SCAPS-1D to do simulations on CuO based solar cells using ZnO, TiO 2 , CdS and ZnSe as buffer layers. The cell characteristics are analysed by varying different material properties. CuO/ZnO showed highest efficiency ~20%. interface defect however impacts the of this significantly. layer thickness has shown little impact cell. Further, we optimized absorber thickness, carrier concentration well. effect electron affinity also been investigated. tried understand...
Abstract In this paper, we have used Cesium tin-germanium triiodide (CsSnGeI 3 ) perovskite-based solar cells (PSC). Here, SnO 2 and CuSCN been as electron transport hole layers, respectively. We optimized the performance parameters of device using an open-source software known Solar cell capacitance simulator (SCAPS–1D). varied thickness absorber layer to understand its impact on efficiency proposed cell. also interface defects defect density optimize device. Further, ETL HTL with respect...
A comprehensive study on the behavior of gate-all-around (GAA) Tunnel Field Effect Transistors (TFET) with different dielectrics in single dielectric-based structure as well stacking is reported. The chosen so to have better gate control over channel ensuing characteristics device for analog parameters investigated. To get full benefit out device, most optimized value work-function chosen.

Perovskite materials have been proven to be a competent choice for an efficient solar cell. The most used perovskite utilize lead as one of the components which impose restrictions over environmental issues. Hence, we made careful search environmentally friendly materials. Cesium tin-germanium triiodide (CsSnGeI3) is has shown better efficiency. This study absorber layer, ZnO (ETL) and CuSCN (HTL). We Solar cell capacitance simulator (SCAPS-1D) software simulation proposed device. To...

Abstract In this article, a label-free biosensor with single cavity that uses negative capacitance heterojunction charge-plasma-based tunnel FET (NC-HJ-CP-TFET) is presented and examined. To increase ON-state current, ferroelectric material (Si:HfO 2 ) has been added to stack gate insulator low energy bandgap (Si0.5Ge0.5). terms of biosensing properties, comparisons have made between NC-HJ-CP-TFET Si-based NC-CP-TFET. The different bio-analytes employed in work are Streptavidin (K = 2.1),...
