Professor Michael Grätzel at EPFL’s School of Basic Sciences has been awarded an honorary doctorate from the University of Gabès (Tunisia).
One of the most important researchers in chemistry of our time, Professor Michael Grätzel received an honorary doctorate from the University of Gabès, a public university located in southern Tunisia with headquarters in Gabès.
The official announcement reads: “By order of the Minister of Higher Education and Scientific Research of July 14, 2023, the University of Gabès awards an Honorary Doctorate to Professor Michael Gratzel, Swiss national, Professor of Higher Education at the Ecole Polytechnique Fédérale de Lausanne - EPFL Switzerland, in the field of science and technology.”
About Professor Michael Grätzel
Professor Grätzel is world-renowned for inventing the first dye-sensitive solar cell in 1991 with chemist Brian O’Reagan. Just as plants use chlorophyll to turn sunlight into energy, the “Grätzel cells” use industrial dyes, pigments or quantum dots stimulated by sunlight to transmit an electrical charge. Within fifteen years of the original invention, Grätzel evolved the cells into an applied technology that is now being developed in universities and companies worldwide.
Having discovered molecular photovoltaics, Grätzel’s research has focused on designing mesoscopic photosystems based on molecular light harvesters that convert light very efficiently to electricity. He is credited with moving the photovoltaic field beyond the principle of light absorption via diodes to the molecular level. Recently his research engendered a second revolution in photovoltaics prompting the advent of perovskite solar cells. In just a single decade, their power-conversion efficiency increased from 3% to over 26%, rivaling and even exceeding the performance of conventional photovoltaics.
Grätzel also applied his innovative mesoscopic design concept to enhance the power of lithium-ion batteries and to create photoelectrochemical cells that efficiently generate chemical fuels from sunlight, opening up a new path to provide future sources of renewable energy that can be stored.
Grätzel currently directs EPFL’s Laboratory of Photonics and Interfaces within the Institute of Chemical Sciences and Engineering (ISIC). His 1,750 publications have received over 450,000 citations and have an h-index of 295. In 2019, Stanford University ranked Grätzel first of 100,000 top scientists across all fields.
