Dai Research Group
Jackson State University
Emerging Nanomaterial and Energy Laboratory
The Dai research group focuses on energy conversion, energy saving, and energy storage with an emphasis on photovoltaics, light-emitting diodes, photodetectors and lithium-ion batteries. Dai group research includes two aspects. (1) structuring engineering of perovskite solar cells, LEDs, and photodetectors toward high stability and high efficiency devices. (2) nanosized metal oxide synthesis for lithium-ion batteries The Dai group offers research opportunities for graduate, and undergraduate students, who are interested in our research. Our lab is located at JHS Room 254, Jackson State University.
