Researchers at the University of Rome Tor Vergata's Centre for Hybrid and Organic Solar Energy (CHOSE), in collaboration with Poland-based Saule Technologies, have demonstrated a large-area flexible perovskite solar module with a fully scalable deposition technique.

The results show the optimization of PTTA and perovskite layer deposition by blade-coating, with the final fabrication of a flexible perovskite module with a PCE of 10.51% over 15.7 cm², showing outstanding light stability of FPSM with a T80′ of 730 h and a recovery efficiency in the dark showing a T80″ of 1560 h, the most stable in the literature reported so far.

GCL Optoelectronic Materials and SC-Solar have signed a strategic cooperation agreement to jointly develop and promote tandem perovskite solar cells.

Under the agreement, both companies will be working closely together to develop the equipment and production line for tandem perovskite cells. They will share resources and find ways to complement each other’s strengths with respect to process technology and fabrication equipment. GCL Optoelectronic Materials is a subsidiary of vertically integrated solar enterprise GCL. SC-Solar is a subsidiary of J.S. Machine, which develops packaging and manufacturing solutions for many industries.

Researchers at the Dresden University of Technology (TUD) have announced the fabrication of a solar cell based on all-inorganic cesium-lead iodide (CsPbI₃) perovskite, which is also sometimes referred to as 'black perovskite'.

TUD researcher Yana Vaynzof said that the choice of this specific material was motivated by the fact that it shows superior stability as compared to the commonly used organic-inorganic lead halide perovskites.

researchers at the Okinawa Institute of Science and Technology Graduate University (OIST), led by Professor Yabing Qi, have demonstrated that creating a raw material used for perovskite solar cells in a different way could be key to the success of these cells.

“There’s a necessary crystalline powder in perovskites called FAPbI₃ , which forms the perovskite’s absorber layer,” explained one of the lead authors, Dr. Guoqing Tong, Postdoctoral Scholar at OIST. “Previously, this layer was fabricated by combining two materials – PbI₂ and FAI. The reaction that takes place produces FAPbI₃. But this method is far from perfect. There are often leftovers of one or both of the original materials, which can impede the efficiency of the solar cell.”
