After a long wait due to COVID, we finally received the visit at UC of our international collaborator Professor Ching W. Tang. During his visit, Professor Tang participated in the 2023 Workshop on Organic Electronics with a Keynote Talk on his professional and personal life on the discovery and development of OLEDs. National collaborators Professors Loïk Gence and Ignacio Jessop also gave exciting talks on their research. Postdoctoral researchers, graduates, and undergraduate students participated in the poster sessions of the Workshop organized by DIPOG and CIEN-UC.
Also, Professor Tang held several meetings with colleagues from different universities and schools to discuss their research results and ideas. As a group, current graduate and undergraduate students also presented their results. Exciting ideas were discussed for possible research collaborations.
We sincerely thank Professor Tang for his first and hopefully not last visit to Chile and for all the academic and social activities we had during his visit.

As every second semester, the elective course "Solar Cells" (QIM517) was offered to undergraduate students in Chemistry. As part of the course activities, students evaluated the efficiency of different commercially available solar cells outdoors. Also, students practiced their communicative skills by presenting in English a critical analysis of scientific articles on Photovoltaics. Congratulations to all!

Héctor defended his thesis "Investigación bibliográfica comparativa de las propiedades optoelectrónicas de derivados de benzoditiofeno y sus análogos benzodifurano y benzodiselenofeno como dadores de electrones en dispositivos fotovoltaicos orgánicos". Special congratulations to Héctor for his work and dedication during the pandemic, as he was able to transfer from an experimental to a bibliographic thesis project.
Below is a picture from the Group right before the pandemic started. We hope to have the proper celebration soon.

As each year, we will be sponsoring postdoctoral researchers interested in applying to FONDECYT Postdoctorado 2020. This year, the application deadline will be by the end of July. The postdoctoral researchers must prepare their own 2-to-3 years research proposals. The proposals must be related to the following topics:
Organic photovoltaics: synthesis, device fabrication by thermal deposition, and device characterization.
Perovskite photovoltaics: synthesis, device fabrication by thermal deposition, and device characterization.
For questions and inquiries, please contact Prof. Angel at faangel@uc.cl
