Science Today, Technology Tomorrow!
This review highlights the progress in the emerging field of both integrated PSC-SC photocapacitors and PSC-LIB photobatteries in detail, including new device concepts, operation mechanisms, and the performance for each part and the whole device. We further analyze the existing challenges and limitations of the […]
Herein, we demonstrate resilient, high-efficiency triple-cation perovskite solar cells (PSCs) by incorporating carbon dots (CDs) derived from human hair into the perovskite film synthesis. It is found that a toluene-based antisolvent containing CDs results in the formation of a bilayer structure where a wave-like textured […]
Stable, low‐dimensional‐network perovskite materials with tailored molecular dimensionality are promising materials for optoelectronic devices including solar cells, light emitting diodes, luminescent solar concentrators, and photodetectors with enhanced performance and stability. This review summarizes the research progress and challenges in this area, providing insights into the research direction in the future.

We develop an approach that combines molecular dimensionality control and interfacial passivation of perovskite layers using a novel post-device treatment (PDT) with the vapour of ethylene-amine salts of different carbon chain lengths to improve both efficiency and stability of the PSCs. The effect of a […]
A method to form 1D pyrrolidinium lead iodide (PyPbI3) in situ atop photoactive 3D methylammonium lead iodide (MAPbI3) using pyrrolidine posttreatment is reported. As compared with 3D MAPbI3, 1D PyPbI3 has a wider bandgap and is more environmentally stable, and it serves as a tunneling […]
Excellent work by Disheng have been choosed as front cover for the ACS Applied Materials & Interfaces Journal.
The work focuses on perovksite solar cell, using 2D Ruddlesden–Popper (PA)2PbI4 perovskites formed by n-propylammonium iodide with PbI2 produce a superhydrophobic surface to maintain the long-term stability of the perovskite layer against moisture-induced decomposition.
