Quasi-2D perovskites are known for their long-term environmental stability. In this system, bulky spacers expected to inhibit ion migration and reduce interfacial nonradiative recombination. However, it also presents challenges charge transportation at the same time. As a result, possibility great potential of such quasi-2D wide band gap (WBG) solar cells have rarely been explored. Here, we specialize in formamidinium-based WBG perovskites, obtaining preferential crystal orientation perovskite film. To obtain better performance, quantum wells (QWs) regulation strategy higher preference low-dimensional interface layer is proposed. The QWs adjusted by binding capacity solvent long-chain molecules. importance QW distribution stability further investigated work. 1.70 eV achieved exhibit an efficiency 20.18% with VOC 1.27 V maintain 95% initial performance under 1 sun illumination over 500 h stable operation.

Tin perovskites are considered promising candidates for realizing high-performance, lead-free perovskite solar cells (PSCs). Despite prominent progress made through bulk optimization, unsatisfactory interfaces between tin and charge transport layers critical obstacles to boosting device performance. Herein, we address this issue by introducing piperazine dihydroiodide (PDI) ferrocene (Fc) at the interface of perovskite/C60 synergistically improve interfacial transport. Specifically, PD+ interacts with formamidinium ions (FA+) form an dipole, Fc establishes π-π conjugation C60. These effects significantly electron extraction reduce energy losses. As a result, efficiency PSCs is remarkably improved from 10.62% 13.65%, accompanied enhanced stability. This work highlights importance modulation in toward efficient eco-friendly photovoltaics.

Abstract Tandem solar cells (TSCs) based on wide bandgap (WBG) perovskites have gained significant attention for their higher power conversion efficiency (PCE) compared to single‐junction cells. The role of WBG perovskite (PSCs) as the sub‐cell in tandem consists absorbing high‐energy photons and producing open‐circuit voltages ( V OC ). However, PSCs face serious phase separation issues, resulting poor long‐term stability substantial loss TSCs. In response, researchers developed a range strategies mitigate these challenges, showing promising progress, comprehensive review is expected. this review, we discuss mechanism organic–inorganic hybrids all‐inorganic perovskites. Additionally, conduct an in‐depth investigation various enhance stability, including component engineering, additive interface dimension control, solvent encapsulation. Furthermore, application TSCs summarized detail. Finally, perspectives are provided offer guidance development efficient stable field
