Abstract
Research on reducing lead (Pb) leakage in flexible and rigid perovskite solar cells (PSCs) simultaneously is limited, with issues including high material cost or low adsorption efficiency. In this study, we developed a cost-effective (0.8 $/m2) and flexible mercaptosuccinic acid-modified polyvinyl alcohol (MMP) film with high Pb-adsorption capacity for rigid and flexible substrates. The formed ester and thiol groups binding to Pb2+ endowed the MMP film with excellent Pb-adsorption capacity. Combined with polydimethylsiloxane (PDMS), the PDMS-MMP film enabled a Pb sequestration efficiency (SQE) of 99% for rigid and flexible PSCs and modules, with no negative impact on their performance, operational stability and bending stability. This is the first study to achieve a 99% SQE in rigid and flexible PSCs and modules at a low cost, marking a significant advancement toward the safe commercialization of perovskite photovoltaic products.
