“Since we are already working on the scaling up of these materials for large-scale solar cells, it is pretty straightforward to modify the procedures to fabricate light emitting devices as well,” NTU materials science and engineering assistant professor Nripan Mathews said in a release. “The fact that it can also emit light makes it useful…
