Integrated Lead/Iodine Management for Sustainable Perovskite Solar Modules.

ABSTRACT: The environmental hazards posed by the release of toxic lead ions (Pb²⁺) and volatile iodine species remain a major obstacle to the large-scale commercialization of perovskite solar modules. Here, we propose a dual-function adsorbent-porphyrin-modified whitlockite nanocomposites (WH&Por), which simultaneously captures volatile iodine via surface-coated porphyrin and adsorbs Pb²⁺ through the whitlockite matrix, forming an integrated pollutant barrier throughout the entire lifecycle of perovskite devices. Experimental results show that even under severe mechanical damage with a WH&Por loading of just 0.25 mg/cm², the protection system prevents the leakage of lead and iodine, demonstrating excellent environmental safety performance. In addition, we developed a
