Abstract
This project aims to explore the use of melanin as a passivation layer in perovskite solar cells (PSCs) to address critical challenges such as stability, defect passivation, and moisture resistance. Melanin's unique properties, including its active functional groups (C=O, C-OH, COOH, N-H, S=O, S-CH3), chelation capabilities, and hydrophobic sulfonated groups, make it an excellent candidat…
