COMPARATIVE ANALYSIS OF THE EFFECT OF ANTISOLVENTS OF TOLUENE DMF AND DMSO ON THE STABILITY OF PEROVSKITES SOLAR CELLS

This research work delves into a comparative analysis of Perovskite solar cells crafted using

different antisolvents, namely DMF, DMSO/DMF, and TOL/DMF. The investigation focused

on assessing their structural and optical properties, as well as their solar cell efficiency and

stability. Notably, the perovskite layer formed with DMF displayed numerous pinholes, while

the use of TOL/DMF as a mixed solvent yielded a pinhole-free layer. Spectral analysis

revealed heightened light absorption in the perovskite layer produced using TOL/DMF

antisolvent, surpassing those created with DMF and DMSO/DMF antisolvents. Remarkably,

the TOL/DMF mixture led to a higher efficiency of the solar cell compared to DMF and

DMSO/DMF anti-solvents. This enhanced efficiency was attributed to the superior

crystallinity, compactness, and reduced band gap energy of perovskite films generated with

TOL/DMF antisolvent. Additionally, the TOL/DMF-fabricated perovskite film exhibited

outstanding stability, enduring for 600 hours before degradation, a marked improvement over

the DMF and DMSO/DMF variants that maintained stability for only 550 and 420 hours,

respectively. These findings underline the critical influence of antisolvent choice in

optimising the fabrication, efficiency, and stability of Perovskites solar cells.
