The technology of perovskite solar cells (PSC) is getting close to breaching the consumer market. Yet, one current challenges reduce toxicity during their fabrication by reducing use toxic solvents involved in process. A good solubilization lead halides used hybrid preparation required, and it only possible with polar solvents. mixture dimethylformamide (DMF) dimethyl sulfoxide (DMSO) most popular solvent combination for a precursor solution. DMF necessary ensure dissolution iodide, but also...
With simpler manufacturing processes and production costs lower than by one‐fifth of those for silicon solar cells, dye‐sensitized cells (DSSCs) are among the most promising technologies third‐generation possessing capability producing electricity under cloudy conditions low or artificial light in comparison to other technologies. Although large‐scale commercialization DSSCs is inhibited their power conversion efficiency. To boost efficiency, several approaches have been implemented,...
Herein we present a comparative study among different mesoporous electron transporter layers (ETLs), namely nanometric m-TiO2, m-SnO2 and quantum dots (QDs), deposited by spray coating method. The experimental data correlated with the photovoltaic parameters indicate that SnO2 layer obtained from deposition of in-house prepared QDs solution is best candidate between three used ETLs. use presents smaller agglomerates composed 3 nm NPs resulting in formation thinner, more uniform, compact ETL,...
Since the discovery of graphene in 2004, 2D materials have been subject extensive research, particular, phosphorene due to its anisotropic properties. The aim this study is, therefore, improve efficiency dye‐sensitized solar cells (DSSCs), considered be next generation cells, by using material. To end, a phosphorene/black carbon hybrid material is prepared and used as counterelectrode DSSCs. This work also demonstrates stability manufactured devices under different aging conditions. results...
Replacing lead atoms in halide perovskite materials is of significant importance for the development environmentally friendly solar cells. In this paper, we investigated effect doping MAPbI2.6Cl0.4 hybrid (MA-methyl ammonium) with non-toxic elements, such as alkaline earth metal ions (Mg2+) and transition (Zn2+). The structural, morphological, optical properties prepared samples were analyzed using X-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force (AFM), UV-Vis....
Electronic and stability properties of quasi-2D alkylammonium perovskites are investigated using density functional theory (DFT) calculations validated experimentally on selected classes compounds. Our analysis is focused perovskite structures formula (A)$_2$(A$'$)$_{n-1}$Pb$_n$X$_{3n+1}$, with large cations A = butyl-, pentyl-, hexylammonium (BA, PA, HXA), small A$'$ methylammonium, formamidinium, ethylammonium, guanidinium (MA,FA,EA,GA) halogens X I, Br, Cl. The role the halogen ions...
