Square micrometer sized free standing organometallic sheets and their Square Centimeter sized multilayers on solid substrates
Macromolecular Rapid Communications, 2013Co-Authors: Zhikun Zheng, Thomas Bauer, Antonella Rossi, Payam Payamyar, Andri Schütz, Andreas Stemmer, Junji Sakamoto, Carlos Ruizvargas, Dieter A SchluterAbstract:Oligofunctional terpyridine-based monomers are spread at an air/water interface, where they are connected with transition metal salts such as Fe(II) into mechanically coherent monolayer sheets of macroscopic dimension. The conversions of these processes are determined by XPS for several monomer/metal ion combinations. The sheets are transferred onto TEM grids, the 20 × 20 Square micrometer sized holes of which can be spanned. AFM indentation experiments provide in-plane elastic moduli which are compared with naturally occurring sheets such as graphene. The new organometallic sheets are also used to create multilayer assemblies on Square Centimeter length scales on solid substrates. Finally some directions are provided where this research can lead to in future and where its application potential lies.

carbon film electrode based Square Centimeter scale planar perovskite solar cells exceeding 17 efficiency
Materials Science in Semiconductor Processing, 2020Co-Authors: Junyan Xiao, Chao Peng, Xinxin Zhang, Chi Mao, Qin Yao, Jie Zhong, Yong Peng, Fuzhi Huang, Yibing ChengAbstract:Abstract Carbon electrode-based perovskite solar cells have shown some advantages in materials cost and long term stability compared to the metal electrode-based devices. Among all the reported carbon electrode techniques, self-adhesive carbon film electrode via press transfer process can achieve high PCE comparable with the Au electrode device in small area perovskite solar cells (∼ 0.1 cm2). Herein, we further promote the carbon film electrode to match the practical Square-Centimeter scale device. Pre-assembled with highly conductive substrates as graphite paper or aluminum foil, the double layered composite carbon electrode can significantly reduce the series resistance, thus retaining the high photoelectric performance of large area device (1 cm2). Especially with the graphite paper/carbon film electrode, a highest PCE of 17.02% was obtained, which achieved 92% of the PCE of 18.56% in small device. The soft and compressible nature can be the superiority of graphite paper as conductive substrate in carbon film based electrode compared with aluminum foil.
