Introduction
His research interests focus mainly on highly efficient and stable perovskite solar cells. In 2018, the high-efficiency perovskite/copper indium gallium selenide thin-film tandem cell was successfully prepared for the first time in the world by him. The result was officially certified by the National Renewable Energy Laboratory under the U.S. Department of Energy. He published the result in Science as the first author and co-corresponding author. In 2024, he found that strong polar solvents in the perovskite precursor desorb the self-assembly molecules (SAMs), which are used as the hole transport layer for inverted perovskite solar cell, if they are anchored on ITO substrate by hydrogen-bonded, rather than covalently bonded. He used atomic-layer deposition to create an indium tin oxide substrate with a fully covalent hydroxyl-covered surface for SAM anchoring, as well as a SAM with a trimethoxysilane group that exhibited strong tridentate anchoring to the substrate to solve this issue. The result was published in Science as well.
He has published over 40 scientific papers on top-level journals such as Science, Nature Photonics, Nature Energy, Energy & Environmental Science, and Advanced Materials in the field of next generation solar cells.
