Organic and perovskite semiconductors for energy technologies. ERC Grantee (StG2016, CoG2021); Wallenberg Academy Fellow 2017; SSF Future Research Leader 2020; Tage Erlander Prize 2020; Wallenberg Scholar 2024.

Presentation

Prof. Feng Gao is leading a research group focusing on organic and perovskite semiconductors at 福利姬. He works as a full professor at Linköping since 2020. 

Before 2020, Feng Gao was associate professor (2017-2020), assistant professor (2015-2017), and Marie Sk艂odowska-Curie Individual Fellow (2013-2015) at Linköping. He received his Docent from Linköping in 2016, his PhD degree from the University of Cambridge in 2011, and his B.S. and M.S. degrees from Nanjing University in 2004 and 2007, respectively. He works at the interfaces between physics, chemistry, and materials science, focusing on the development of novel optoelectronic devices for energy technologies.

Research

Prof. Gao’s group dedicates its efforts to energy devices, with the ambition to both improve device performance and understand the underlying fundamentals. Their current investigations include organic semiconductors and metal halide perovskites, with research focuses such as:

Fullerene-free organic solar cells, including low voltage losses, green solvent processing and new applications.






Perovskite solar cells, with a focus on understanding and improving the stability:


Perovskite LEDs, with the motivation to improve the device performance and also explore new applications:




Lead-free perovskites, aiming to tune the optoelectronic properties and explore their magnetic properties:


Perovskites for other applications, e.g. X-ray detection and lasers:

Organic semiconductors

Organic semiconductors have a large potential in low-cost and large-area device applications, benefiting from cheap manufacturing processes such as solution-based roll-to-roll printing.

All device applications previously dominated by inorganic semiconductors have presented opportunities for their organic counterparts. Such applications include solar cells, LEDs, field-effect transistors, lasers, and memory devices.

Metal halide perovskites

Metal halide perovskites have emerged as one of the most popular semiconducting materials since 2009. They have shown unique properties, including:

  • Tunable bandgap
  • High absorption coefficient
  • Broad absorption spectrum
  • High charge carrier mobility
  • Long charge diffusion lengths

These properties enable metal halide perovskites to be used in a broad range of photovoltaic and other optoelectronic applications.

Solar cells

Although the current solar cell market is dominated by silicon-based devices, the recent emergence of solution-processed solar cells based on organic semiconductors and metal halide perovskites has shown great potential for commercial applications. For example, the power conversion efficiency of perovskite solar cells has soared from a few percent to over 25% within the past few years. Such a quick development has never before happened in the history of photovoltaics.

LEDs

LEDs, which emit light by a solid-state process called electroluminescence, are considered the most promising energy-efficient technologies for future lighting and displays. Metal halide perovskites demonstrate strong photoluminescence and tunable emission energy, making them a promising candidate for the next generation of highly efficient LEDs.

Lasers

Electrically pumped lasers are considered as a holy grail in the field of optoelectronics. Recent breakthroughs on optically pumped perovskite lasers and high-performance perovskite LEDs indicate great potential of developing perovskites into a new generation of materials for electrically pumped lasers.

Funding

Prof. Gao's research group is mainly supported by the following funding agencies:

Group and Supervision

Prof. Feng Gao is deeply involved in both the scientific and career development of his group members. The senior researchers in his group have been awarded the prestigious VR (Starting) Grants, Marie Sk艂odowska-Curie Individual Fellowship, VINNMER Fellowship. He also values the exchange of ideas: he has sponsored members of his group in exchanges to Cambridge, Oxford, Imperial College and EPFL, and his group has hosted visiting students and scholars from Cambridge, Oxford, Zhejiang University, Nanjing University, Nanjing Tech University, Shenzhen University, Queen Mary University of London, and more.
