Welcome to Wang Group @Nanjing Tech!

The research in our group focuses on perovskite optoelectronic devices. We are actively engaged in exploring various aspects of this field, such as the preparation of materials, the design and fabrication of devices, and the analysis of underlying mechanisms. Our primary objective is to develop perovskite optoelectronic devices characterized by high efficiency and stability. Specifically, we are focusing on the development of perovskite light-emitting diodes (LEDs), solar cells, lasers, and photodetectors. In addition to perovskite devices, we also maintain a keen interest in studying other optoelectronic materials and devices, such as organic solar cells.

Through our ongoing research efforts, we seek to not only deepen our fundamental understanding of perovskite materials and devices, but also to pave the way for their practical applications in various fields. By pursuing excellence in both scientific discovery and technological innovation, we strive to make significant contributions to the rapidly growing field of optoelectronics.
