Alternative solvent helps produce environmentally-friendly tin perovskite solar cells
Perovskite solar cells are widely regarded as the next generation photovoltaic technology. However, they are not yet stable enough in the long term for widespread commercial use. One reason for this is migrating ions, which cause degradation of the semiconducting material over time.
Tin perovskite study points to more stable lead free solar cells
Berlin, Germany (SPX) Dec 04, 2025 Perovskite solar cells are under development as candidates for next generation photovoltaic modules, but commercial use remains limited by long term instability driven in part by migrating ions in the absorber layer. A team from Helmholtz-Zentrum Berlin (HZB) and the University of Potsdam has now measured ion densities in four widely used perovskite compounds and found substantial differences be
The Helmholtz-Zentrum Berlin and the University of Potsdam have found a much lower ion density in tin perovskites compared to conventional lead perovskites. This could solve an environmental and stability problem for the perovskites considered to be photovoltaic material of the future.Perovskite semiconductors have a recognized high potential for photovoltaic applications, in which research has already achieved efficiencies by 27 percent and in …
