Researchers from The University of Queensland, EPFL, Griffith University and NIMS have studied how doping can help in overcoming some of perovskite solar cells' drawbacks. The researchers found that the efficiency and thermal stability of the doped cells significantly outperformed those that were not doped.

“The PSCs that had doped cells showed a remarkable solar conversion efficiency that exceeded 21 per cent,” the team reported.

The German Research Foundation (DFG) is funding a new project, kicked off on October 5, 2021, called 'project HIPER-LASE'. The new project will explore the potential of perovskite semiconductors for realizing an on-chip electrically pumped laser.

Integrated photonic-circuits could trigger the next technological revolution in microelectronics. The prerequisite, however, is the availability of a cost-effective and scalable manufacturing technology. An excellent candidate for this task is the photonics platform based on silicon/silicon-nitride. What is still missing though, is an integrable laser source. In the DFG-funded project HIPER-LASE, AMO and partners RWTH Aachen University, the University of Wuppertal and the University of Siegen will explore the potential of perovskite semiconductors for realizing an on-chip electrically pumped laser.
