Two nanoGe Conferences celebrated in Oxford last week showed the extraordinary strength of the development of perovskite solar cells and the great general interest of quantum dots fundamental physics and solar cells.
International Conference of Fundamental Processes in Semiconductor Nanocrystals, 2014, Oxford, United Kingdom
International Conference Solution processed Semiconductor Solar Cells, 2014, Oxford, United Kingdom
The Conference on Solution processed semiconductor solar cells, being celebrated in Henry Snaith’s place, obtained massive fluence from perovskite solar cells people. Many presentations and discussions showed that the questions are being centered about relevant properties of the perovskite solar cell. After some period of puzzlement by the extraordinary novel characteristics, now everybody starts to present the questions and comes up with original explanations, that undoubtedly will be addressed in the the next months in the literature and in discussion forums. It is a nice generating moment in this field. The very fast development of materials was highlighted for example by Yang Yang presentation of the noted Science paper with efficiency over 19%. New interesting applications were suggested by Miyasaka exploiting the ferroic properties of the perovskite. Emilio Palomares came up with a happy metaphor about the current interest of the perovskite for new researchers with respect to the previous families of hybrid solar cells. The presence of quantum dot solar cells was less than in previous years but still showed innovative results especially about doping of nanocrystalas and formation of heterostructures. These questions as well as ultarfast phenomena and new applications (bio, LEDs) were also discussed in the conference on fundamentals by an impressive list of speakers and participants.
Both conferences benefited from the presence of Prof. Rudolph Marcus, Nobel laureate, that was very interested in the electron transfer problems and in the perovskite solar cells. It was wonderful and inspiring to talk to the great master.
