Add to ORKGThesis: S.M., Massachusetts Institute of Technology, Department of Electrical Engineering and Computer Science, 2019Cataloged from PDF version of thesis.Includes bibliographical references (pages 81-86).In this thesis, I have studied the electroluminescence (EL) properties of photovoltaic (PV) devices based on "Organometallic Perovskites" which exhibit high power conversion efficiencies of approximately 23%. Aside from single-junction current-voltage characteristics, these devices exhibit low voltage light emitting diode (LED) operation with thermally activated sub-bandgap voltage turn on and efficiency roll-off occuring before the bandgap voltage. with a maximum electroluminescence quantum efficiency (LED-EQE) of appoximately 14%, with an ...
