  • Revolutionize solar energy with a breakthrough material from Lithuanian chemists. Improved efficiency and stability for perovskite solar cells. Patent filed, commercialization potential high.

A team of chemists from Kaunas University of Technology in Lithuania has developed a novel material for perovskite solar cells, which can improve their stability and efficiency. The material, a 9,9′-spirobifluorene derivative, forms a solvent-resistant three-dimensional polymeric network after thermal cross-linking, which can be used as a hole-transporting layer in both regular and inverted architecture solar cells. This new material has shown better energy conversion efficiency and stability compared to conventional hole transporting materials.

The research team has filed for a patent for the novel material at the EU, U.S., and Japanese patent offices, indicating high commercialization potential. The collaboration between Lithuanian and Japanese scientists has been crucial in achieving these results, with successful partnerships leading to advancements in perovskite solar cell technology. The development of this new material is seen as a significant step towards the widespread adoption of solar energy, with projections suggesting that half of the world’s electricity could be produced from solar energy by 2050.
