About

Yiying Wu is a Distinguished Professor in the Department of Chemistry and Biochemistry at The Ohio State University. He received his B.S. in chemical physics from the University of Science and Technology of China in 1998 and his Ph.D. in chemistry from the University of California at Berkeley in 2003, working under Professor Peidong Yang. He conducted postdoctoral research with Professor Galen D. Stucky at the University of California, Santa Barbara, before joining the faculty at Ohio State in 2005. His research focuses on materials chemistry for energy conversion and storage, including projects on dye-sensitized solar cells, electrocatalysis, and lithium-ion batteries. His work involves materials synthesis, electrochemistry, and photoelectrochemistry, with particular interest in oxide semiconductors, graphene, dye molecules, and hybrid materials. Wu's contributions include developing nanostructured materials for high-efficiency solar cells and batteries, as well as studying electrocatalysts for solar fuels. He has received awards such as the Cottrell Scholar Award in 2008 and the NSF-CAREER award in 2010, and was promoted to full professor in 2014.

• Intramolecular Electric Field Construction in Metal Phthalocyanine as Dopant‐Free Hole Transporting Material for Stable Perovskite Solar Cells with >21 % Efficiency

  Angewandte Chemie International Edition · 2021-01-21 · 155 citations

  articleOpen access

  Low conductivity and hole mobility in the pristine metal phthalocyanines greatly limit their application in perovskite solar cells (PSCs) as the hole-transporting materials (HTMs). Here, we prepare a Ni phthalocyanine (NiPc) decorated by four methoxyethoxy units as HTMs. In NiPc, the two oxygen atoms in peripheral substituent have a modified effect on the dipole direction, while the central Ni atom contributes more electron to phthalocyanine ring, thus efficiently increasing the intramolecular d…

• Grain Boundary Engineering with Self-Assembled Porphyrin Supramolecules for Highly Efficient Large-Area Perovskite Photovoltaics

  Journal of the American Chemical Society · 2021-10-19 · 139 citations

  articleOpen access

  Grain boundary management is critical to the performance and stability of polycrystalline perovskite solar cells (PSCs), especially large-area devices. However, typical passivators are insulating in nature and limit carrier transport. Here, we design a supramolecular binder for grain boundaries to simultaneously passivate defects and promote hole transport across perovskite grain boundaries. By doping the monoamine porphyrins (MPs, M = Co, Ni, Cu, Zn, or H) into perovskite films, MPs self-assemb…

• Predictive Design Model for Low-Dimensional Organic–Inorganic Halide Perovskites Assisted by Machine Learning

  Journal of the American Chemical Society · 2021-08-06 · 112 citations

  articleOpen accessSenior authorCorresponding

  Low-dimensional organic-inorganic halide perovskites have attracted interest for their properties in exciton dynamics, broad-band emission, magnetic spin selectivity. However, there is no quantitative model for predicting the structure-directing effect of organic cations on the dimensionality of these low-dimensional perovskites. Here, we report a machine learning (ML)-assisted approach to predict the dimensionality of lead iodide-based perovskites. A literature review reveals 86 reported amines…

• Olefin-Linked Cationic Covalent Organic Frameworks as Host Materials for Lithium–Sulfur Batteries

  ACS Applied Materials & Interfaces · 2025-09-01 · 3 citations

  article

  Lithium–sulfur batteries (LSBs) are an emerging energy storage system with high volumetric and gravimetric energy densities. However, a significant challenge is the shuttle effect caused by intermediate polysulfide species. The polysulfide species aids in reducing active material retention and degrading battery performance. Covalent organic frameworks (COFs), a crystalline class of porous polymers, have emerged as an excellent platform for constructing sulfur host materials that inhibit the shut…
