Cities are looking to the circular economy to help the climate

Halide perovskite solar cells have in recent years emerged as a potential alternative to silicon-based photovoltaics due to their outstanding performance, having reached energy conversion efficiency comparable to the currently available silicon counterparts in less than a decade of research. Therefore, in addition to vast academic interest, industries are paying close attention to the development of perovskite-based photovoltaics.

What started as a 10-year-old child’s persistence has become  a career for Elisabeth Pesavento ’21.  “I told my mom that I really wanted to play the horn,” Pesavento said. “And you know, like all mothers, she’s said, ‘Oh that’s nice. It’s a very beautiful instrument.’ But I just kept asking and kept asking until finally she was like, ‘Wow, I guess she really does want to play the horn.’”  After Pesavento finally got her French horn, she traveled the world with the instrument.
