Prof. Trilok Singh and our team at the Department of Energy Science and Engineering (DESE) has been extensively working on finding a potential solution to overcome the defects, stresses, and lower reproducibility issues of perovskite-based devices.

In our recent publication in SMALL Journal (Wiley), we managed to fabricate Perovskite solar cells under ambient conditions with higher efficiency and stability. Further, by carefully selecting the molecule, we have proposed an anti-solvent-free device fabrication strategy to manage the reproducibility of devices.

To prevent the lattice mismatch at the electron transport layer (ETL)/Perovskite interface, we have employed Guanidine sulfate salt (Gua-S). Gua-S potentially reduces interfacial stresses due to the comparable size of Gu and FA ions. Moreover, these salts can tackle cationic and anionic defects in the film. This is because of the presence of amino anchoring groups (-NH2) and sulfate anion (SO42−) in the Gua-S salt.

“The device demonstrated exceptional stability, maintaining 87% of its initial PCE after 2000 hours of operation. This highlights the potential of Gua-S as an effective approach for improving both the performance and long-term stability of PSCs. Such innovative solution of using anti-solvent-free techniques will promote the upscaling of perovskite solar cells under ambient conditions”.
