This year's Göran Gustafsson Prize in Physics goes to LiU professor Feng Gao. His research focuses on how new materials can be used for the next generation of solar cells and LEDs, among other things. The total prize money is SEK 7.5 million.

Cost, technical performance and environmental impact – these are the three most important aspects for a new type of LED technology to have a broad commercial impact on society. This has been demonstrated by LiU-researchers in a new study.

In a study published in Nature, researchers at LiU have developed a method to recycle all parts of a perovskite solar cell repeatedly without environmentally hazardous solvents. The recycled solar cell has the same efficiency as the original one.

Large-scale production of organic solar cells with high efficiency and minimal environmental impact. This can now be made possible through a new design principle developed at Linköping University.

Professor Feng Gao has been granted SEK 31 million from the Knut and Alice Wallenberg Foundation over five years to develop a new type of X-ray technology. The goal is a flexible material that can improve X-ray detector image quality.

This summer, Dr Alex Gillett is arriving at LiU from the University of Cambridge, UK. He has been awarded a Wallenberg Academy Fellows grant and will use the funding to build his own lab to conduct research in the field of optoelectronics.

Dr Nakul Jain, a postdoctoral researcher working on organic solar cells (OSC) at Linköping University, has been granted a scholarship from King Carl XVI Gustaf´s 50-year fund for his work to improve the efficiency and stability of OSCs.

Max Karlsson, who obtained his PhD from the Department of physics, chemistry and biology at Linköping University, has been doubly recognised for his thesis on the dynamics of blue-emitting metal halide perovskites for light-emitting diodes.

Material used in organic solar cells can be used as light sensors in electronics. This is shown by researchers at LiU who have developed a type of sensor able to detect circularly polarised red light. Their study is published in Nature Photonics.

Researchers at LiU have developed a digital display screen where the LEDs themselves react to touch, light, fingerprints and the user’s pulse, among other things. Their results could be the start of a whole new generation of digital displays.
