Perovskite Solar Cells with Dual Light Absorber Layers for Performance Efficiency Exceeding 30%

Abstract

The present work represents a comparative modeling and performance optimization of three device configurations: ITO/ZnO/Cs2BiAgI6/Spiro-OMeTAD/Au, ITO/ZnO/CIGS/Spiro-OMeTAD/Au, and ITO/ZnO/Cs2BiAgI6/CIGS/Spiro-OMeTAD/Au. The concern of low light absorption by materials such as Cs2BiAgI6 and CIGS limits its application as a light absorber in photovoltaic devices. Nevertheless, the light absorption by the device can be enhanced by the inclusion of a second light active layer composed of the graded active layer of both Cs2BiAgI6/CIGS, which effectively boosts the efficiency of the device configuration. In this study, SCAPS-1D software was employed for analyzing the proposed solar cell models. The optimized output parameters achieved include J SC of 31.89 mA/cm2, V OC of 1.108 V, FF of 85.01%, and PCE of 30.10%, which approaches the Shockley-Queisser limit.

“…[6][7][8][9] Perovskite solar cells (PSCs) with organic-inorganic hybrids have signicantly improved device design and better optical absorption, prolonged chargecarrier lifespan, high charge-carrier mobility, low trap density, and low exciton binding energy; materials with more control. [10][11][12][13][14] However, the organic cation's volatility and thermal instability poses the severe problems for their widespread commercial uses. 15,16 An inorganic Sr 3 SbI 3 perovskites can signicantly advance the development of solar cells owing to its In 2 S 3 as ETLs was investigated at varying layer thickness, bulk defect density, doping density, interface density of active materials, working temperature, the generation rate and recombination rates, quantum efficiency (QE), and current density-voltage (J-V) were executed.…”

Comparative Study of Distinct Halide Composites for Highly Efficient Cesium-Based Perovskite Solar Cells

“…Extensive PV study related to CsPbI 2 Br at varying halide compositions is needed to comprehend the influence of different halide compositions on the output of the device. Therefore, in this work, we intend to investigate and compare the properties of various perovskite materials, concerning their different halide materials in relation to their performance parameters via the SCAPS-1D simulator. − A comparative study of various perovskites, such as CsPbBr 3 and CsPbI 2 Br, is carried out to help us understand the distinct performance and their effect on parameters and to further work for a highly efficient and more suitable stable perovskite.…”

Investigation of a novel inorganic cubic perovskite Ca3PI3 with unique strain‐driven optical, electronic, and mechanical properties

“…[9][10][11][12] Recently the inorganic perovskites achieved a greatest power conversion efficiency of over 13% with excellent device permanence. [13][14][15][16] However, despite these promising characteristics, their widespread application is hindered by limited stability. [17] The stability of these perovskites is highly vulnerable in real-world situations because of their intense susceptibility to moisture, air, light, and temperature.…”
