Revolutionizing Perovskite Solar Cells with Nanomaterial Regulation

• Revolutionary nanomaterial doping strategy boosts perovskite solar cell efficiency to 24.5%. Researchers at CAS and Henan University lead the way in sustainable energy innovation.

Researchers at CAS and Henan University have developed a nanomaterial-regulated doping strategy to increase the efficiency of perovskite solar cells (PSCs) to 24.5%. By using inorganic SnSO as a dopant to oxidize and regulate the organic hole transport layer spiro-OMeTAD, they were able to enhance the charge transport capability and optimize the energy level position of the HTL.

The traditional doping method using Li-TFSI had low efficiency and could lead to decreased compactness and conductivity of the film. The new method developed by the researchers allows for fast and reproducible control of the oxidation process, resulting in a high PCE of 24.5% and stable performance even under harsh conditions. This study could pave the way for further improvements in the efficiency and stability of PSCs, making them more commercially viable.
