Finally, several new insights are proposed to further optimize the photovoltaic properties of 2D PerSCs. The structural stability, phase stability, and environmental stability are discussed for all-inorganic, tin-based, and 2D/3D PerSCs. Furthermore, the exact balance between stability and efficiency needs to be reconsidered. ![]() For 2D PerSCs, three critical factors of carrier transport, energy level alignment (ELA), and light management are summarized to further enhance the photovoltaic performance. In this review, we focus on the crystallographic characteristics and crystal growth of 2D perovskites from the perspectives of fabrication methods, solvent engineering, and component engineering. The Stretchly program indicator shows how much time is left until the next mini-break It is possible to go to a short or long break without counting the time It is possible to pause or reset the countdown It is possible to adjust the duration and interval of short (mini) and long breaks On/off display of notifications before the start of. However, the power conversion efficiency (PCE) of 2D perovskite solar cells (PerSCs) still needs to catch up to their 3D counterparts at present. ![]() The success of introducing diverse organic cations in three-dimensional (3D) organic–inorganic hybrid perovskites to form two-dimensional (2D) or quasi-2D perovskites, including Ruddlesden–Popper (R–P), Dion–Jacobson (D–J), and alternating cations in the interlayer (ACI) structures, highlights the research progress for 2D perovskite-based optoelectronic materials and devices. Hello folks, Are you using Stretchly - The break time reminder app If yes, can you help me by sharing your experience with me by filling this small 1 min.
