The present invention concerns a perovskite solar cell provided with a polymer-porous template composite material for absorbing toxic metal ions. 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.
