Description
We demonstrate a polymer-assisted strategy to improve FAPbBr3 wide bandgap perovskite solar cells by incorporating poly(methyl methacrylate) (PMMA) into the antisolvent. PMMA passivates defects via coordination with Pb2+ ions, enhancing crystallinity, reducing sub-bandgap states, and suppressing non-radiative recombination. This results in improved film quality, a Voc increase of over 100 mV, enhanced efficiency, and greater device stability.
