Solid-State Nuclear Magnetic Resonance

For my first internship in the master’s I joined Dr. Manjunatha Reddy’s team to study the stability of organic semiconductor and perovskite materials for their use in organic solar cells using solid-state NMR (ssNMR). I was attracted by this high-end technique that posed a challenge to me to understand as I had no previous formation on it. By the end of the internship I felt confident in my ssNMR spectroscopy skills as well as article writing skills, contributing to one published paper and another that got rejected. This was a very enriching experience as I learned the importance of collaboration since we analyzed samples sent from colleagues in different parts of the world while they also performed other kinds of complimentary characterization techniques. Additionally, I learned about the article writing and publishing process, which was quite enriching. The results show that organic solar cells using the PM6:Y6 system are good for indoor use while lead halide perovskites’ stability and efficiency for solar cells are being improved.
