I’ve been fortunate enough to attend the European Materials Research Society (E-MRS) Spring Meeting twice now during my PhD. The first time I presented at this meeting was during my first year (after completing our first MRes project) and the second time was between May 22 and 26 this year, which is the third year of my PhD. So, what’s changed between now and then besides the orientation of the sign?
Well it turns out that quite a lot has happened in my field of solar cell research, in terms of the understanding of solar cell materials I was already familiar with (and their current shortcomings preventing them from being on top of all our roofs already!) and new materials altogether that are emerging as contenders for new, efficient solar cell technologies. There was even a talk on using atomicly thin solar cells in outer space, beaming the electricity back to Earth via microwaves, which overcomes the issue of storing energy generated from sunlight when it’s dark on Earth. I assume the devices would be thin enough to be semi-transparent since I personally would feel a bit grumpy being in the shade for weeks or months if I lived directly below! The big plenary session in the middle of the conference highlighted various hot topics in the broader field of materials research including developing sensors for ‘electronic noses’ and thin layers of materials that are so sensitive to changes in humidity that they could potentially be used for ‘touchless’ as opposed to ‘touchscreen’ phones due to the humidity in our fingers. Some of the research into electronic noses is inspired by this guy below and his massive antennae:
So clearly the science has changed in two years, which isn’t altogether surprising given how rapidly changing a field science is in general; but what else has changed? The venue was different this year, with the conference being held in Strasbourg from now on (as opposed to Lille). Strasbourg was a lovely city, I’d go so far as to say unnecessarily pretty, it was showing off really. It’s also a nice city for a conference since it was pretty small so you could easily see most of it in a short space of time. The conference social was quite like the one in Lille, although this time the dancing also involved a giant horn, presumably this is something associated with Strasbourg but not Lille, unless it’s just another recent trend, like electronic noses?
Then I suppose the last thing to comment on that has changed between EMRS 2015 and 2017 is myself! I’m not shorter (despite appearances in the two photos with the EMRS signs), but I found the experience of the conference different this time around. Firstly, I felt less nervous presenting this time, as 2015 was the first time I’d presented at a conference. EMRS 2015 had been my favourite conference so far in terms of the scientific content and 2017 did not disappoint. However, I think what I gained from attending the various talks was different this time around. I found that a lot more of the concepts were more familiar, but the main difference I noticed (as someone whose research is based on a computer with simulations as opposed to in a lab), was that I felt a lot more familiar with presentations on various experimental studies this time around. I largely attribute this to the ‘wild card’ second MRes project you get to do during your first year (which I hadn’t done before I attended the EMRS in 2015), where I got to get some hands-on experimental experience and very much benefited from working with fellow CDT solar cell researchers Oli Weber, Mako Ng as well as Professors Mark Weller and Chris Bowen at the University of Bath. So, overall, I’d have to say attending the EMRS Spring Meeting again has left me feeling very grateful for the diverse experience I got during the first year of my PhD. At the time, I must admit I felt like a bit of a fish out of water in the labs, but I’m very glad for that experience now!
