Recently, Professor Wu Jihuai’s team from College of Materials Science & Engineering and Engineering Research Center of Ministry of Education for Environmentally Friendly Functional Materials of Huaqiao University (HQU) have made major progress in perovskite solar cells research. Within less than two months, they published three high-level papers inACS Energy Letters,Small MethodsandSmall, three renowned international journals in materials and chemistry.

Li Guodong, PhD student of Grade 2019, published a paper entitled "Efficient and Stable 2D@3D/2D Perovskite Solar Cells Based on Dual Optimization of Grain Boundary and Interface" as the first author inACS Energy Letter.

Deng Chunyan, PhD studentof Grade 2020, published as the first author inSmall Methodsa paper entitled "Surface Reconstruction and In Situ Formation of 2D Layer for Efficient and Stable 2D/3D Perovskite Solar Cells".

Liu Xuping, PhD student of Grade 2018, also published a first-author paper entitled "Phthalideand 1-Iodooctadecane Synergistic Optimization for Highly Efficient and Stable Perovskite Solar Cells" inSmall.

The above researches were funded by Key Program of National Natural Science Foundation of China - StraitsJoint Fund (U1705256) and Projects ofNational Natural Science Foundation of China (51972123, 21771066) and Graduate Innovation Fund of HQU.
