“…[26,27,30] Organic-inorganic Sn-based perovskites are the best choice for replacing Pb-based PSCs because of their excellent photovoltaic performance owing to their similar and even better optoelectronic properties (e.g., lower optical bandgaps, high absorption coefficients, and higher charge carrier mobilities) than those of Pb-based perovskites. [31,32] In 2014, Snaith and Kanatzidis independently developed the MASnI 3based solar cell, which achieved an efficiency of around 6%. [33,34] Recently, Wang et al achieved a power conversion efficiency (PCE) of 7.78% using a MASnI 3 -based planar heterojunction structure.…”

This study uses computational analysis to comprehensively investigate lead‐free organic–inorganic CH3NH3SnI3 (MASnI3)‐based perovskite solar cells (PSCs). The optoelectronic properties of MASnI3 are investigated using density functional theory with first‐principles calculations, highlighting its potential for photovoltaic applications. Key findings include the determination of a crucial bandgap (0.97 eV), identification of the onset of photon absorption at energies exceeding 2 eV, and characterization of material properties, such as the absorption and extinction coefficients, reflectivity, and refractive index. Device optimization through simulations explores parameters such as layer thickness, defect density, and different charge transport layers, resulting in a remarkable enhancement in the power conversion efficiency to 16.72%. Additionally, this study focuses on the influence of the working temperature, series resistance (R s), and shunt resistance (R sh) on the photovoltaic device performance. Hence, a high photovoltaic efficiency in MASnI3‐based PSCs can be achieved by carefully optimizing the device performance parameters and effectively managing the defect densities.

“…Embedding metallic nanoparticles such as gold (Au), silver (Ag), or copper (Cu) in the active layer plays a crucial role in reducing exciton quenching and cell resistance, significantly improving PCE [19,20]. Localized surface plasmon resonance (LSPR), in which the surface of a metal nanostructure glows when exposed to light, utilizes the light trapping for metalized solar cell with various plasmonic structures, contributing to enhance the light absorption [21][22][23]. By embedding these plasmonic nanostructures in solar cells and illuminating them, the light-harvesting capability can be improved using the localized surface plasmon resonance principle, which improves light scattering efficiency [24,25].…”

Herein, the Fabry-Perot (F-P) interference of cesium silver bismuth bromide (Cs2AgBiBr6) double perovskite solar cells has been analyzed by modulating the optical path length of each layer step by step using the finite-difference time-domain (FDTD) method. The study was performed pass through three main steps. In step 1, for the fluorine-doped tin oxide (FTO)/Cs2AgBiBr6 double perovskite/gold (Au) architecture, we increased the absorption layer thickness from 150 to 600 nm at intervals of 150 nm and then predicted the optical performance including the absorption and reflection. In step 2, titanium dioxide (TiO2) layer was added between FTO electrode and Cs2AgBiBr6 double perovskite and then scaled from 20 to 200 nm at intervals of 20 nm. In the analysis process, short-circuit current density (Jsc) repeatedly fell and rose as the TiO2 layer thickness increased, and when TiO2 layer thickness is 100 nm, Jsc showed the highest value of 13.91 mA/cm2. In step 3, by applying a spiro-OMeTAD layer between the Cs2AgBiBr6 double perovskite absorption layer and Au electrode, the Jsc showed a continuous increase with slight decrease as the spiro-OMeTAD layer thickness increased from 110 to 200 nm, and when the spiro-OMeTAD layer thickness was 200 nm, Jscwas calculated as 14.57 mA/cm2, which is the highest value in the range. In the case of the optimal condition of full structure device, the Fabry-Perot resonance peaks were discovered at 477, 520, 572, 659, and 778 nm five wavelength regions, and the influence of the Fabry-Perot resonance on the generation rate inside the absorption layer on the 520, 572, and 659 nm monochromatic wavelength light was analyzed according to the position in the device. Our study approaches the Cs2AgBiBr6 double perovskite solar cell from an F-P cavity perspective and shows the light trapping phenomenon of the device according to the optical path length modulation.

The heterogeneity of perovskite film crystallization along the vertical direction leads to voids and traps at the buried interfaces, hampering both efficiency and stability of perovskite solar cells. Here, bovine serum albumin‐functionalized Au nanoclusters (ABSA), combined with heavy gravity, high surface charge density, and strong interactions with the electron transport layer, are designed to reconstruct the buried interfaces for not only high‐quality crystallization, but also improved carrier transfer. The ABSA macromolecules with amine function groups and larger surface charge density interact with the perovskite to improve the crystallinity, and gradually migrate towards the buried interface, healing the defective voids, hence suppressing surface recombination velocity from 3075 to 452 cm s−1. The healed buried interface and the higher surface potential of ABSA‐modified TiO2 lead to improved carrier extraction at the interface. The resulting solar cell attains a power conversion efficiency of 25.0% with negligible hysteresis and remarkable stability, maintaining 92.9% of their initial efficiency after 3200 h of exposure to the ambient atmosphere, they also exhibit better continuous irradiation stability compared to control devices. These findings provide a new metal‐protein complex to eliminate the deleterious voids and defects at the buried interface for improved photovoltaic performance and stability.
