PCM-buffered perovskite for adaptive thermal management and enhanced thermal stability in perovskite solar cells

Haider Ali Tauqeer, Abdul Basit, Shizi Luo, Guiqiang Li et autres

Third generation perovskite solar cells have higher absorption properties, carrier mobility, longer diffusion length, lower cost and tunable bandgap than traditional solar cells. Although the long-term stability and commercial viability of perovskite solar cells remain a challenge, their use in tandem configurations …

Solvent-Driven Surface-State Reconstruction of ZnMgO for Stable Blue QLEDs

Jing Zhou, Xuejiao Zhou, Noor Zaman, Lavrenty G. Gutsev et autres

Blue QLEDs face a critical challenge in balancing high luminous efficiency with operational stability, primarily due to uncontrolled electron injection and interfacial trap-assisted recombination. Here, we present a facile aqueous ZnCl2 post-treatment strategy to engineer ZnMgO (ZMO) electron transport layers (ETLs). This …

Applying Texturization Methods for Luminescent Down‐Shifting Films to Enhance the Light Absorption in High‐Efficiency Photovoltaic Devices

Yu An, Sıla BEKTAŞ, Ning Yang, Gence Bektaş et autres

Photon management offers a promising strategy to mitigate optical losses and improve the efficiency of photovoltaic devices. In most down‐shifting studies, the isotropic emission of down‐shifting materials limits the photon utilization. Herein, we combine inverted‐pyramid texturization with luminescent down‐shifting films to minimize …

Synergistic Surface Copassivation of PbS Colloidal Quantum Dot Films for Efficient Inverted Solar Cells

Noor Zaman, Jin Zhou, Yiqun Li, Tongjun Zheng et autres

Inverted p-i-n structure lead sulfide colloidal quantum dots (PbS CQDs) solar cells are more process compatible and flexible in interface engineering, but their efficiency is still behind that of n-i-p conventional structures. Their performance is restricted by surface defects and interfacial recombination …

Co-passivation of Buried Interfaces in Perovskite Solar Cells with Sulfonate and Amine Salts

Biniyam Zemene Taye, Zhuoneng Bi, Alexander V. Zhilenkov, Shuguang Cao et autres

Interfacial defects remain a key limitation of the performance of perovskite solar cells (PSCs). Using first-principles density functional theory (DFT) and SCAPS-1D device simulations, we examine how sulfonate and primary amine salts can jointly passivate the SnO 2 /perovskite buried interface. The …

Advancements in Self‐Assembled Molecules to Hybrid Self‐Assembled Molecular Interlayers for Optimized Hole Transport Layer in Inverted Perovskite Solar Cells

Haider Ali Tauqeer, Tongjun Zheng, Shizi Luo, Lian Xiong et autres

Inverted (p-i-n) perovskite solar cells (PSC) have demonstrated significant promise compared to the conventional n-i-p architecture, owing to their improved operational stability, reduced hysteresis, and low-temperature fabrication process. These advantages make inverted devices particularly attractive for tandem and flexible applications. Self-assembled molecules …

Complementary Molecular Passivation of Multiple Surface Defects for Efficient and Stable Inverted Perovskite Solar Cells

Yupeng Zheng, Tongjun Zheng, Shizi Luo, Haider Ali Tauqeer et autres

Abstract A complementary passivation strategy employing the simultaneous use of phenylethylammonium iodide (PEAI) and ethylhydrazinoacetate hydrochloride (EHACl) is developed to mitigate multiple surface defects in perovskite films. PEAI mainly aims at vacancy defects and tends to induce quasi‐2D/3D interface reconstruction, while rich …
