Advanced ink formulations could be the key to turning perovskite solar cells (PSCs) from heroes of academic labs into commercially successful products. Researchers at KAUST have developed a perovskite ink tailor-made for a mass manufacturing process called slot-die coating, producing PSCs that captured solar energy with high efficiency. The ink could also be coated onto silicon to create perovskite/silicon tandem solar cells that capture even more of the Sun’s energy.

Iain McCulloch, the director of the KAUST Solar Center, has been elected as a Fellow of the Royal Society. McCulloch, who is a KAUST professor of chemical science, as well as a Chair in Polymer Materials at Imperial College London, has made discoveries in chemical design and synthesis to control the assembly of organic semiconducting molecules to form ordered structures with specific electrical and optical properties, for use in a range of devices including transistors and solar cells.

Long-lived inverted perovskite solar cells can achieve efficiencies close to that of highly efficient yet fragile conventional perovskite solar cells, researchers at KAUST have shown. The discovery could lead to perovskite solar panels that have operational lifetimes and light-capturing efficiencies that rival traditional silicon solar panels, but that are significantly simpler, less energy-intensive and less expensive to make.
