New Perovskite Seminar Series - MIT-Harvard Center for Excitonics

9.15.2015

Metal-halide perovskites are creating a great deal of recent attention for their use in high performance solar cells. Power conversion efficiencies have jumped from 3% to over 20% in just 3 years, making them competitive with commercially available thin film technologies. They also show tremendous promise in a variety of optoelectronic applications including light-emitting diodes (LEDs) and lasers. There are several efforts on perovskites already under way at MIT, and there are many others who are interested in working with these materials.

The Perovskite Seminar Series provides a platform to connect researchers at MIT working on perovskite solar cells and other optoelectronics and to keep us all up-to-date with the latest in the field. The series, sponsored by the Center for Excitonics, will be monthly and consist of a seminar with invited faculty or a lunch talk with postdocs or senior graduate students. It is hoped that the seminar series will be of interest to faculty, staff and students and will facilitate fruitful discussions and collaborations.

To hear about upcoming seminars, please sign up to the mailing list here: http://mailman.mit.edu/mailman/listinfo/perovskite-seminars. Please contact the series coordinator Sam Stranks (stranks@mit.edu) if you are interested in giving a seminar or with any questions.
