Quantum developments boost organic solar cells and communications
13 May 2021
Researchers at Gothenburg and KTH universities, both based in Sweden, achieve quantum photonics breakthroughs.
Organic solar cells have many advantages compared with traditional silicon-based solar cells. They can be manufactured cheaply at a large scale using printing presses, and they are light, malleable and flexible.
A problem, identified by the Gothenburg researchers, is that todayâs organic solar cells are not as stable and effective as silicon-based solar cells. In a recently published study, the researchers have taken on this problem and say they have found a way that can lead to more cost-effective solar cell technology. The work is described in Nature Communications.

A team of Louisiana researchers, including a group from the Tulane University School of Science and Engineering, has developed a smart quantum technology that could have real-world applications to quantum networks and future quantum communications systems used in the military.
Ryan Glasser, an associate professor of physics at Tulane, and his team in the Department of Physics, collaborated on the study with researchers from Louisiana State University. The study was featured on the cover of the March 2021 issue of
“Recent developments in optical technologies have resulted in extremely high information transfer rates using the spatial properties of light i.e. images (and more complex structured beams),” Glasser said. “However, a difficulty in such communications using light through free-space is that turbulence can severely distort the beams, resulting in errors in the communication.”

Scientists at the Institute of Nano Science and Technology (INST), Mohali, Punjab have produced electron gas with ultra-high mobility, which can speed up transfer of quantum information and signal from one part of a device to another and increase data storage density and memory.
The research on high-mobility 2d-electron gas(2DEG) at the interface of two insulating oxide layers may open up a new field of device physics, especially in the field of quantum technology applicable for next-generation data storage media and quantum computers
The need for attaining new functionalities in modern electronic devices has led to the manipulation of property of an electron called spin degree of freedom along with its charge. This has given rise to an altogether new field of spin-electronics or ‘spintronics’. It has been realised that a phenomenon called the ‘Rashba effect’, which consists of splitting of spin-bands in an electronic system, might play
