A University of Queensland PhD student in the School of Chemistry and Molecular Biosciences has won a prestigious international award at the Materials Research Society’s 2016 Spring meeting in Phoenix (USA).

Mr Qianqian (Vincent) Lin won the Materials Research Society Graduate Student Gold Award for a presentation on next-generation optoelectronics.

Awards Committee chair Professor Albert Polman of the University of Amsterdam, and 2016 Society President Professor Kristi Anseth  of the University of Boulder, Colorado, said the awards honored and encouraged graduate students whose academic achievements and current materials research displayed a high level of excellence and distinction. 

“The Award is a direct reflection on the outstanding education provided by The University of Queensland,” they wrote.

They said the society sought to recognise students of exceptional ability who showed promise for future substantial achievement in materials research. 

Mr Lin is a PhD student in the Centre for Organic Photonics & Electronics, supervised by co-director and ARC Discovery Outstanding Research Award Fellow Professor Paul Meredith, and ARC Laureate Fellow Professor Paul Burn FAA FRSC.

A Master of Science graduate of Zhejiang University China, he has published more than 17 publications, including two Nature Photonics papers co-authored with UQ researchers including Professor Burn and Professor Paul Meredith of COPE.

Last year he was nominated as the only representative of the UQ Chapter of the Optical Society of America (OSA) to attend OSA’s student leadership conference with a travel grant to the US.  

Professor Burn said: “Mr Lin is an outstanding young scientist who has made seminal contributions to the field or organohalide lead perovksites.”

His Nature Photonics paper on lead perovskite solar cells has been cited a remarkable 152 times since it publication in 2015, Professor Meredith said.

Mr Lin’s award-winning presentation explored photodetection systems, which are used in a number of ways, from imaging biological cells to taking pictures with a cellphone camera.

“A photodetector is composed of an array of devices called photodiodes, which absorb light to produce electric current,” Mr Lin said.

“In my study, photodiodes that respond to a narrow range of wavelengths without requiring a filter were fabricated using an emerging class of perovskite semiconductors.”

“The photodiodes represent a new breed of photodetectors.  And their performance rivals that of current commercial systems, highlighting the potential of these materials in producing low-cost, next-generation optoelectronics.”
