摘要

通过在钙钛矿前驱体膜上构建致密的超平面4-叔丁基硫杯[4]芳烯封盖层来设计钙钛矿形成动力学，展示了钙钛矿薄膜“超分子受限生长”的新概念。超分子限制方法使钙钛矿薄膜的制备具有高度可重复性，具有均方根10nm和电子均匀性，这大大减少了器件间和批间太阳能电池器件的功率转换效率变化。得到的钙钛矿薄膜在两个界面上均表现出光致发光量子产率>； 10%和表面复合速度<； 100 cm s−1。

Reproducible Fabrication of Perovskite Photovoltaics via Supramolecule Confinement Growth

Highlights

Demonstrating a new concept of “supermolecule confined growth” of perovskite thin films by constructing a compact, ultraflat 4-tert-butylthiacalix[4]arene capping layer atop perovskite precursor film to engineer the perovskite formation dynamics.
The supramolecule confined approach enabled the highly reproducible fabrication of perovskite films with a root mean square < 10 nm and electronic homogeneity, which significantly minimized the power conversion efficiency variations for both device-to-device and batch-to-batch solar cell devices.
The obtained perovskite films exhibited photoluminescence quantum yield > 10% and surface recombination velocities < 100 cm s⁻¹ for both interfaces.

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand. Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields. Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
