Opto-electronic devices using ionic hybrid organic-inorganic materials

The talk will focus on two type of opto-electronic device, one the inverse of the other, namely light-emitting electrochemical cells (LECs) and Perovskite based solar cells.
LECs are one of the simplest type of molecular electroluminescent devices. Latest developments on ionic transition-metal complex based LECs including their R2R deposition on flexible substrates will be presented.
Methylammonium lead iodide perovskite based photovoltaic devices have recently emerged as an interesting alternative for thin film solar cells. In the four years since, the performance of perovskite-based solar cells has improved rapidly to reach efficiencies as high as 20 % The talk will focus on metal oxide free methylammonium lead iodide perovskite cells with high power-conversion efficiencies and without hysteresis prepared using vacuum based deposition processes. We will present recent developments in these vacuum deposited metal oxide free perovskite solar cells.


Dr. Henk Bolink is a full time researcher at the University of Valencia, Spain. He obtained his PhD in Materials Science at the University of Groningen, The Netherlands in 1997. He then joined DSM Research and in 2001 he went to Philips, to lead the materials development activity of Philips´s PolyLED project. His current research interests encompass: inorganic/organic hybrid materials and mixed electronic/ionic charge transporting materials and their integration in opto-electronic applications.
