2022 Rank Prize: Important Contribution to Perovskite Semiconductor and Optoelectronic Science

  Rank Prize is one of the top scientific awards in the UK and is considered as the “Nobel” prize in optoelectronics and nutrition. The winners mainly include those who have made important contributions in the global optoelectronic science or nutrition field.

  In 2022, the Rank Prize for optoelectronics was awarded to seven leading international scientists, who took the lead in developing new solar cell technology based on perovskite semiconductors, which are expected to play a key role in the field of solar power generation in the future.

  The solar simulator provides stable and continuous irradiance to illuminate the solar cells, which can avoid characterization errors due to the slow response time of the solar cell. With the quantum efficiency measurement system, in addition to the EQE (External Quantum Efficiency) spectrum analysis of perovskite solar cells, it also provides Jsc (short-circuit current density) for the short-circuit current of the solar cell. The result of the comparison is used to prove the authenticity of the experiment. At the same time, Enlitech’s solar simulator and the KA-6000 software provide short-circuit current monitoring over time, which can prove the stability of perovskite solar cells!

About the seven Rank Prize-winning scientists

Professor Michael Graetzel

  Michael Graetzel is a professor at the Ecole Polytechnique Fédérale de Lausanne (EPFL). He is the first to study the reaction of energy and electron transfer in mesoscopic systems and how to generate electricity and fuel from sunlight. The most exciting breakthrough in the recent history of photovoltaics is that his dye-sensitized solar cells led to the advent of perovskite solar cells.

Dr Akihiro Kojima

  Dr. Akihiro Kojima studied the optical properties of organic-inorganic layered perovskite compounds in 2004. From 2005 to 2010, he was engaged in the research of organic metal halide perovskite compounds applied to dye-sensitized solar cells. He started to develop flexible photovoltaic cells in 2010.

Dr Michael Lee

  Dr. Michael Lee is currently the editor of Science Robotics, who was the editor of Nature Electronics and Nature Communications. He has published research results in various journals (including Science and Nature Communications) and is the designated as inventor of international patents.

Professor Tsutomu (Tom) Miyasaka

  Tsutomu Miyasaka focuses on photoelectrochemical and hybrid photovoltaic cells, especially halide perovskite solar cells. His awards include: Chemical Society of Japan Award (2017), PVSEC Hamakawa Award (2017), Clarivate Analytics Citation Honor Award (2017), Japan Society of Applied Physics Achievement Award (2019), and Ichimura Academic Award (2020).

Professor Nam-Gyu Park

  Nam-Gyu Park is a professor of chemical engineering at Sungkyunkwan University (SKKU) in South Korea. In 2012, Park’s team took the lead in reporting a long-term stable perovskite solar cell, opening up a new field of perovskite photovoltaic research. His team is developing high-efficiency perovskite solar cells and large-area processing technology for commercialization and long-term stability.

Professor Sang Il Seok

  Sang Il Seok is a distinguished professor of the Department of Energy and Chemical Engineering at the Ulsan National Institute of Science and Technology (UNIST) in South Korea. His research focuses on functional inorganic-organic hybrid materials and devices. His team first proposed an inorganic-organic hybrid perovskite heterojunction solar cell, which operates in a completely different way from perovskite-sensitized solar cells. Currently, his team holds the world record for the most efficient perovskite solar cell, with efficiency of 25.5%.

Professor Henry Snaith FRS

  Henry Snaith is a physicist dedicated to new materials and devices for photovoltaic solar conversion. He found that when the new type of solar cell material, perovskites, are integrated into a thin-film device, the high-efficiency solar cells can be produced. Furthermore, the manufacturing is very easy and low-cost. He promises to use photovoltaic power generation to provide electricity to the world and achieve zero emissions.
