Reference excerpt

Mohammad Khaja Nazeeruddin (born 1957 in Thumboor, Andhra Pradesh, India) is an Indian-Swiss chemist and materials scientist who conducts research on Perovskite solar cells, dye-sensitized solar cells, and light-emitting diodes. He is a professor at EPFL (École Polytechnique Fédérale de Lausanne) and the director of the Laboratory for Molecular Engineering of Functional Materials at School of Basic Sciences.

Career Nazeeruddin received a PhD in chemistry from the Osmania University in Hyderabad, India. He served as a lecturer at Osmania University for two years. He then joined the Central Salt and Marine Chemicals Research Institute in Bhavnagar, India. In 1987 he joined EPFL, first as a postdoctoral fellow, and then held several positions as research fellow for seven years. In 2012, he was promoted to "Maître d' Enseignement et de Recherche" (senior lecturer). Since 2014 he has served as full professor at EPFL (École Polytechnique Fédérale de Lausanne) and head of the Laboratory for Molecular Engineering of Functional Materials at School of Basic Sciences based at EPFL's Valais campus. 2023 –2029 Professor and Director for the Institute of Perovskite Photovoltaics and Integrated Optoelectronics, IC, Southeast University, Wuxi, China. 2022 –2029 Emeritus Professor, Faculty of Basic Sciences, ISIC, EPFL, Switzerland. 2012 –2022 Professor, Faculty of Basic Sciences, ISIC, Group for Molecular Engineering of Functional Materials, EPFL, Switzerland. 2009–2014 World Class University Professor, Department of Advanced Materials Chemistry, Korea University (Sejong Campus), Korea. 2014-2019 Brain Korea Plus (BKPLUS 21), Department of Advanced Materials Chemistry, Korea University. 2014-2023 Visiting Professor, King Abdul-Aziz University, Jeddah, Saudi Arabia. 2024-2029 Professor, Imam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia. 2023-2029 Research Fellow, INTI, International University, Malaysia. 2014-2021 Participated in the Program of Introducing Talents of Discipline to University ("111" Program) Supported by the Ministry of Education of China, North China Electric Power University. 2024-2026 Guest Professor in Haixi Institutes, Chinese Academy of Sciences. 2023-2029 Advisory Board member of the University of Sharjah- College of Sciences 2024-2026 International Iberian Nanotechnology Laboratory Scientific Advisory Board. He has also had several affiliated while working and employed at EPFL, such as World Class University Professor (2009–2014) and BKPLUS 21 (2014–2019) at the Department of Advanced Materials, Chemistry of the Korea University, and visiting professor at King Abdulaziz University in Jeddah, Saudi Arabia (2014–2023) and at the North China Electric Power University (2014–2021), and an eminent professor at Brunei.

Research Nazeeruddin's research focuses on chemical engineering of functional materials for photovoltaic and light-emitting applications such as Perovskite and dye-sensitized solar cells, and light-emitting diodes. His team conducts research in the area of inorganic chemistry of ruthenium sensitizers that convert solar energy through the use of high surface area nanocrystalline mesoscopic films of oxide semiconductors. These tailored-sensitizers have attracted additional research in dye-sensitized solar cell research. They have synthesized several ruthenium sensitizers (N3, N719 and N749), donor-π-bridge-acceptor porphyrin sensitizers, and near IR sensitizers. A further field of their research encompass organic light-emitting diodes (OLEDs) that are used in the fabrication of digital displays. They contributed novel blue, green, and red phosphorescent iridium emitters for OLEDs. His laboratory is located at the EPFL-Sion Energy center, focusing on organic, inorganic lead halide perovskite solar cells and Light Emitting Diodes research. His laboratory has fabricated blue, green, and red PLEDs with unprecedentedly high external quantum efficiency. His group has investigated solutions (one-step and sequential deposition) and sublimation-deposited perovskite solar cells and obtained a power conversion efficiency of 25%. His group has developed a Perovskite Solar Cells Module (area 26.02 cm2) with an efficiency of 22.4%. Their research has been covered in several international news outlets. These cells and modules are not commercially deployed and much more research and development needs to be done and long-term stability of the cells and modules have yet to be demonstrated. There are numerous leading researchers world-wide working on this problem. Perovskite-based solar cell technology in general is still in the developmental stage and essentially no perovskite-based solar modules have been commercially deployed for harnessing solar power.

Worked examples

Example 1 — a first encounter with Mohammad Khaja Nazeeruddin

Start with the simplest possible case. Write down what Mohammad Khaja Nazeeruddin claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Mohammad Khaja Nazeeruddin before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Mohammad Khaja Nazeeruddin ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Mohammad Khaja Nazeeruddin

In research: Mohammad Khaja Nazeeruddin appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Mohammad Khaja Nazeeruddin in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Mohammad Khaja Nazeeruddin is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1957 births, 21st-century Indian chemists, Academic staff of Osmania University, so understanding it makes those chapters shorter.
In everyday life: Look for Mohammad Khaja Nazeeruddin outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
