ChE-602 - Recent Events in Energy seminar series
Semiconducting perovskites and their corresponding opto-electronic applications have evolved at an impressive speed over the last years. Given the maturity of this technology in terms of performance, a surprisingly number of scientifically challenging questions are still under discussion. The nature of the bandgap transition and the unusual long carrier lifetime is one of these questions, the origin of hysteresis, the nature of the junction and the corresponding field distribution as well as the ultimate mobility of that class of soft ionic semiconductors are other fascinating aspects. In this seminar we will take a closer look to some of these ongoing challenges and finally suggest a surprisingly simple device model to rationalize the origin of hysteresis.
