Scientists at EPFL have increased the power conversion efficiency of dye-sensitized solar cells ("Grätzel cells") beyond 15% in direct sunlight and 30% in ambient light conditions.

A team from the UNIGE, in collaboration with EPFL, reveals how motivation influences the neural circuits of perception and impacts decision-making.

Scientists led by groups at EPFL and the University of Tennessee Health Science Center (UTHSC) explore the elaborate interplay between genes, sex, growth, and age and how they influence variation in longevity. Their results point at fundamental processes of aging that help in improving human healthspan.

In science, specialization pays off – at least when it comes to career impact. That’s the finding of a team of EPFL researchers who looked specifically at this subject.

Physicists at EPFL have developed a formulation to solve the longstanding problem of electron self-interaction when studying polarons – quasiparticles produced by electron-phonon interactions in materials. The work can lead to unprecedented calculations of polarons in large systems, systematic studies of large sets of materials, and molecular dynamics evolving over long time periods.
