Ted Sargent at the University of Toronto has built a reputation over the years as being a prominent advocate for the use of quantum dots in photovoltaics. Sargent has even penned a piece for IEEE Spectrum covering the topic, and this blog has covered his record breaking efforts at boosting the conversion efficiency of quantum dot-based photovoltaics a few times.
Earlier this year, however, Sargent started to take an interest in the hot material that has the photovoltaics community buzzing: perovskite. Now, he and his research team at the University of Toronto have combined perovskite and quantum dots into a hybrid that they believe could transform LED technology.
In research published in the journal Nature, Sargent’s team describes how they developed a way to embed the quantum dots in the perovskite so that electrons are funneled into the quantum dots, which then convert electricity into light.
