Scientists in India modeled the performance of tin-based perovskite (methylammonium tin triiodide) finding that with careful optimizations the material could achieve efficiencies beyond 28%.In the fast-moving development of perovskite solar cells, lead-based materials have led the way in terms of performance, reaching efficiencies beyond 25%. And the push for the commercialization of the technology has also focused on lead-containing materials, in particular methylammonium lead-triiodide. Lead is only present in these materials in small amounts and unlikely to cause a serious environmental issue. ...Den vollständigen Artikel lesen ...
