报告人简介：
Monica Lira-Cantu obtained a PhDdegree in Materials Science at the Materials Science Institute of Barcelona(ICMAB) in Barcelona (Spain, 1997). From 1999 to 2001 she worked as permanentSenior Staff Chemist at ExxonMobil Research & Engineering (formerly MobilTechnology Co) in New Jersey (USA) initiating a laboratory on energy relatedapplications (fuel cells and gas membranes). She returned to Spain in 2002. Sheis Tenured Research Fellow at the Spanish National Research Council (CSIC,Spain) and group leader of the Nanostructured Materials for Photovoltaic EnergyLab (at ICN2, Spain). She has received different awards/fellowships as avisiting scientist to the following laboratories: University of Oslo, Norway(2003), Riso National Laboratory, Denmark (2004/2005), the Center for AdvancedScience and Innovation, Japan (2006) and the Ecole Polytechnique Federal deLausanne, EPFL Switzerland (2015-2018). She has been the PI of several projects(both national, European and with industry), and she is the principalcoordinator of a COST Action Project related to the study of the stability ofOrganic and perovskite solar cells. Her research interests are the synthesisand application of nanostructured materials for Next-generation Thin Film SolarCells: Dye Sensitized, Organic, All-oxide and Halide Perovskite Solar Cells.
报告摘要：
We are moving towards a sustainablesociety powered by renewal energy where solar photovoltaics is one of the mostimportant players. In the past few years, emerging photovoltaic (PV) technologieshave observed an exponential increase in power conversion efficiencies (PCE)with halide perovskite solar cells above 22 %, tandem photovoltaics reaching 26% or dye sensitized solar cells for indoor lighting at the impressive 28.9 %PCE mark. Oxides in solar cells can be found as the main solar absorberresponsible for photon-to-electron conversion, as interfacial layers for thetransport of electron or holes, as part of the conductive metal electrodes(including transparent electrodes) and also as part of photon management. Amongthe many advantages is the ease of fabrication, low cost and enhanced stabilitythat provide to the solar cell. Moreover, new-generation of oxides (e.g. dopedor undoped, binary, ternary, ferroelectric, etc) are slowly breaking groundproviding competitive power conversion efficiencies, enhanced transportproperties or improved UV-light stability, among others. In this talk I willpresent a brief review on the application of binary metal oxides (binary,doped, nanostructured) and complex oxide compounds (ternary, ferroelectric,etc.) as transport layers in Halide Perovskite Solar Cells. We will discusstheir effect on solar cell efficiency and long-term stability of solar celldevices. I will also discuss someinitial results on the defect passivation of halide and oxide defects in orderto enhance device lifetime.
