   Perovskite photovoltaics are gaining increasing common ground to   
   partner with or compete with silicon photovoltaics to reduce cost of   
   solar energy. However, a cost-effective waste management for toxic   
   lead (Pb), which might determine the fate of this technology, has not   
   been developed yet. Here, we report an end-of-life material management   
   for perovskite solar modules to recycle toxic lead and valuable   
   transparent conductors to protect the environment and create dramatic   
   economic benefits from recycled materials. Lead is separated from   
   decommissioned modules by weakly acidic cation exchange resin, which   
   could be released as soluble Pb(NO3)2 followed by precipitation as   
   PbI2 for reuse, with a recycling efficiency of 99.2%. Thermal   
   delamination disassembles the encapsulated modules with intact   
   transparent conductors and cover glasses. The refabricated devices   
   based on recycled lead iodide and recycled transparent conductors show   
   comparable performance as devices based on fresh raw materials. Cost   
   analysis shows this recycling technology is economically attractive.
