In 1991, EPFL scientists Brian O’Regan and Michael Grätzel developed a solar cell inspired by plant photosynthesis. Their dye-sensitized solar cell offered a new way to capture sunlight and turn it into electricity. The idea was simple, but improving its performance took decades of research. About 34 years later, the…
