In the present communication we will focus on the use of fullerenes and fullerenes derivatives in
Perovskite-based Solar Cells.
In our research group we have dedicated a great effort on the preparation and study of novel fullerene derivatives for their incorporation in perovskite solar devices. Thus, we have reported for the first time the use of pristine C70 as ETL in PSCs and the utilization of fullerenes and derivatives as additives in PSCs.
Very recently we have described the incorporation of a Fullerene derivative as HTM (FU7) in PSCs, and also the concept of “fullerene sandwich” perovskite devices.
In this invited talk, we will discuss on these topics, highlighting the potential of the use of fullerene chemistry in order to prepare highly efficient and stable in PSCs.

Juan Luis Delgado obtained his Ph.D. in Chemistry at UCLM (Spain) in 2004 under the supervision of Prof. F. Langa (RSC Fellow). Afterwards, he joined the group of Prof. J.-F. Nierengarten (RSC Fellow), at the ECPM-CNRS (Strasbourg, France) where he worked as a postdoctoral fellow. He then joined the group of Prof. N. Martín (RSC Fellow) at University Complutense of Madrid as a “Juan de la Cierva” postdoctoral researcher. From 2008 to 2014 he was a Senior “Ramón & Cajal” Researcher at IMDEA-Nanoscience (Madrid, Spain). In 2013 he was awarded with the “Young Researcher Award” of RSEQ (Spanish Royal Society of Chemistry)-Lilly Spain and the “Emerging Investigator Award” of RSEQ (Spanish Royal Society of Chemistry)-Sigma-Aldrich Spain. His research interest is mainly focused on the synthesis of organic materials suitable for their utilization in organic photovoltaics, dye sensitized solar cells, light harvesting, artificial photosynthetic systems, and perovskite-based solar devices.
Juan Luis Delgado is an Ikerbasque Research fellow and leader of the Hybrid Materials for Photovoltaics group at POLYMAT in the University of the Basque Country (Spain) since 2014. Juan Luis Delgado has published more than 80 publications (h-Index 27 > 3000 citations) in highly prestigious international journals such as J. Am. Chem. Soc., Ang. Chem. Int. Ed., Chem. Soc. Rev, Energy & Environ. Sci., Chem. Sci., Adv. Energy Mater. and several book chapters

Abstract 

An Overview of Research Activities on Photovoltaic Materials and Devices at METU-GÜNAM

The Center for Solar Energy Research and Application (GÜNAM) is an interdisciplinary research center formed by several research groups from different departments of Middle East Technical University (METU). It has been supported by the Turkish government to create a technical infrastructure in the field of solar energy conversion technologies in the last 9 years. With this support, GÜNAM has become a comprehensive research center in Turkey as well as in the eastern Mediterranean region.

More detailed information can be reached from the web site: www.gunam.metu.edu.tr.

Crystalline Si (c-Si) based solar cells, thin film solar cells, organic and perovskite solar cell, solar thermal electricity are among the research topics of GÜNAM. 20 faculty members and more than 90 graduated students are doing research at the GÜNAM facilities which includes a crystalline Si solar production system for industrial size wafers (156mm x 156 mm), an a-Si cluster tool (with 4 plasma and 2 sputtering chambers) for thin film and heterojunction solar cell development.
In this talk an overview of the research activities at GÜNAM and their outcomes will be given. Following a short presentation of GÜNAM, research results on structuring Si bulk without damaging the surface and wafer slicing by laser, carrier selective contact formation with MoOx and TiO2 towards doping free c- Si solar cells, fabrication of crystalline Si thin film by e-beam evaporation for carrier selective layers on c-Si surface, nanosponge Si with variable band gap for all Si tandem solar cells, nanotexturing Si surface by laser, solution and vacuum based perovskite solar cells for Si tandem applications will be presented.
