Mojtaba’s research investigates emerging semiconductors for electronics applications including solar-photovoltaics and lighting. He aims to develop and incorporate new inexpensive materials in optoelectronic devices to alter the energy landscape by reducing the cost of both energy production and consumption.




Mojtaba is a Materials Scientist and a Research Associate at Cavendish Laboratory and he has five years' experience in entrepreneurship inspired by winning the Cambridge University Entrepreneurs (CUE) competitions. He is a co-founder and technical advisor of Cambridge Materials, a start-up company that develops energy harvesting devices based on emerging semiconductors.

He completed his PhD in 2018 at the Optoelectronics group, Cavendish Laboratory, University of Cambridge, working under the supervision of Professor Sir Richard Friend. His work has addressed a number of important challenges in the development of hybrid perovskite semiconductors and their implementation for broad applications particularly optoelectronic devices and led to a number of key patents and publications in the field. Prior to this, Mojtaba received an MSc in Materials Science and Engineering from École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland where he worked with Professor Michael Grätzel on development and implementation of novel materials in emerging solar cells. 

Research interests

Mojtaba’s research focuses on the optical and electronic properties of emerging semiconductors including metal halide perovskites, nanostructured metal oxides and other organic semiconductors and incorporating them in optoelectronic devices such as solar photovoltaics (PV), photodetectors and light-emitting diodes (LEDs). He investigates novel materials and device photophysics via spectroscopy as a powerful tool to understand their characteristics in different length and time scales, unveil the origin of instability and maximize the output of the optoelectronic devices.

Mojtaba is also involved in exploitation of the academic research into actual products and bridging the gap between fundamental science and technology commercialization.He has active industrial collaborations for technology transfer into multiple emerging markets including photovoltaics, the Internet of things (IoT) and consumer electronics.
