Preferably, the porous template material is a metal oxide framework (MOF) material. An example of a preferred polymer-porous template composite material is PDA-Fe-BTC (polydopamine-Fe1,3,5-benzenetricarboxylate). In experiments mimicking breakage of the solar cell modules, the presence of the polymer-MOF material was shown to result in the capture of lead and thus to reduced leakage of lead.patentEP4076733US2023088203CN115427142EP4076733WO2021122851EP383840068944257
