Michael Grätzel
Swiss professor (born )
Michael Grätzel (born 11 May , in Dorfchemnitz, Saxony, Germany)[3] is a professor at the École Polytechnique Fédérale de Lausanne where he directs the Laboratory of Photonics and Interfaces. He pioneered research on energy and electron transfer reactions in mesoscopic-materials and their optoelectronic applications. He co-invented with Brian O'Regan the Grätzel cell in [1][4][5][6]
Graetzel is the author of over publications,[7] two books and inventor or co-inventor of over 80 patents,[8] he has been the Mary Upton Visiting Professor at Cornell University and a distinguished visiting professor at the National University of Singapore, and is currently a distinguished scientist at King Abdulaziz University.[9] He was an invited professor at the University of California, Berkeley, the École normale supérieure Paris-Saclay and Delft University of Technology.

Dye-sensitized solar cell
Type of thin-film solar cell
A dye-sensitized solar cell (DSSC, DSC, DYSC[1] or Grätzel cell) is a low-cost solar cell belonging to the group of thin film solar cells.[2] It is based on a semiconductor formed between a photo-sensitized anode and an electrolyte, a photoelectrochemical system. The modern version of a dye solar cell, also known as the Grätzel cell, was originally co-invented in by Brian O'Regan and Michael Grätzel at UC Berkeley[3] and this work was later developed by the aforementioned scientists at the École Polytechnique Fédérale de Lausanne (EPFL) until the publication of the first high efficiency DSSC in [4] Michael Grätzel has been awarded the Millennium Technology Prize for this invention.[5]
The DSSC has a number of attractive features; it is simple to make using conventional roll-printing techniques, is semi-flexible and semi-transparent which offers a variety of use

Professor Michael Graetzel is a physical chemist who investigates photo-induced electron transfer reactions in mesoscopic systems and their use to generate electricity and chemical fuels from sunlight.
He is known for his discovery of dye-sensitized solar cells, which engendered the advent of perovskite photovoltaics, constituting the most exciting breakthrough in the recent history of photovoltaics. He used his revolutionary concept of three-dimensional mesoscopic semiconductor junctions also to realize photo-electrochemical devices for the solar generation of hydrogen and reduction of carbon dioxide.
Michael received numerous awards for his scientific achievements, including the Millennium Technology Prize, Balzan Prize, BBVA Foundation Frontiers of Knowledge Award, Marcel Benoist Prize, Global Energy Prize, King Faisal International Science Prize and Rank Prize in Optoelectronics. He obtained a PhD from the Technical University of Berlin and received twelve honorary doctor’s
