    Light Trapping for Absorption Control in Perovskite-Based Photovoltaic Solar Cells

    Nanostructure based perovskite solar cells with high performance are the focus of study in current work, keeping in view the improvement in cell efficiency. In the rst part of the study, a plane-layered solar cell is studied by adding a 1D Photonic Crystal (1D PhC) at the bottom of the cell in order to facilitate the photon rotation process. However, in the second part of the study, it is observed that the addition of grating enhances the light absorption due to photon trapping. Following that, the light absorption of three different structures is compared. The observations reveal that the short-circuit current density (Jsc) is found to be 􀀀39:93mA/cm2, which is 87.29% higher than that for a planar structure exhibiting the short-circuit current density (Jsc) value of 􀀀21:32mA/cm2. Finally, the efficiencies of these nanostructured perovskite solar cells are found to be signi cant. For the proposed solar cell structure an 87.24% improvement in the power conversion efficiency (PCE) is observed, i.e., from 14.03% for the planar structure to 26.27%.

    Optimization study of perovskite-based solar cells using R-soft package

    In this work, we have used the “RSOFT’s Diffract MOD and solar Cell Utility” based on the Rigorous Coupled Wave Analysis (RCWA) technique to analyze the behavior of the perovskite-based solar cell. Here, the RSoft CAD (Photonic Device Tools) was utilized to determine the effect of materials in different layers of a perovskite-based solar cell on the power conversion efficiency (PCE) and other useful parameters, such as the density of the current-voltage (J-V) measurements. Therefore, we chose the perovskite as an active layer, PDMS as a window layer and gold (OR) as a reflective layer. Here, Different ETM and HTM candidates have been suggested. Firstable, HTM was proposed randomly and presented by P3HT and the ETM is presented by TiO2, ZnO, ZnSe and ZnS, and thus, it was found that the best ETM is ZnS because the enhanced PCE increased from 18.30% when we use the ZnSe to 21.19% when the ZnS is chosen. Secondly, the optimum ETM candidate was selected and presented by ZnS, and the two HTM candidates were changed and presented by P3HT and AZO. It was found that the best HTM is the AZO, and the PCE of this perovskite-based solar cell reached the value 21.43%.

    Improve Efficiency and Reduce Cost of Perovskite-Based Solar Cell

    This work utilizing “RSOFT’s Diffract MOD and solar Cell Utility” based on RCWA calculation to analyze the behavior of the solar cell and to compute the PCE (power conversion efficiency) (RSoft CAD photonic device tools) was used to study the effect of the materials used in the different layers of the perovskitebased solar cell on the efficiency of this cell. We used perovskite as the active layer, PDMS as a window layer, ZnS as ETL (electron transport layer) and AZO as HTL (hole transport layer). and make a change of reflective layer from Au (Gold) to different reflective layers candidate have been suggested. So that in the beginning we used gold as a reflective layer, we found the efficiency of this cell estimated at 21.43%, we changed the reflective gold layer with different other reflective layers such as (Al, Cr, Be, Ni, Ti…) in order to increase the efficiency of this solar cell and reduce the cost because the cost of gold is high, we found that the efficiency increased in most of the candidates to reach 24.23% when Be was placed as a reflective layer, and this is a significant increase in the efficiency of the solar cell.

    L'amélioration de l’efficacité et de la stabilité des cellules photovoltaïques à base de pérovskite

    La structure joue un rôle très important sur l’efficacité de la cellule . Les matériaux de la cellule jouent un rôle très important sur l’efficacité de la cellule . Au début quand la première cellule avant l’amélioration de cette cellule le rendement est très bas et la cellule absorbe un petit nombre de photons . Après l’amélioration de la cellule nous avant trouvé une augmentation du rendement et une grande absorption de lumière .
