Michael Grätzel tops new ranking of scientists

EPFL Professor Michael Grätzel is ranked #1 in a list of 100,000 top scientists across all fields. The ranking method is a based on new, more accurate standardized citation metrics developed by scientists led by Stanford University. On August 12, a group of scientists led by Professor John P.A. Ioannides at Stanford University published a paper in the journal PloS Biology outlining a new way to rank scientists by citations and other metrics, without falling prey to common abuses such as self-citation or citation farms. The new method produced a database of over 100,000 top scientists across multiple fields, and was extensively covered by Nature . The ranking places EPFL Professor Michael Grätzel at #1. Grätzel, who directs EPFL's Laboratory of Photonics and Interfaces , is world-famous for inventing the dye-sensitized solar cells ("Grätzel cells") , which became the launchpad for the current development of perovskite photovoltaics. Dye-sensitized solar cells are already manufactured on a multi-megawatt scale, and perovskite photovoltaics are poised to conquer the market in the near future.
