This work gives insights about the crystal formation and spatial heterogeneities on different length scales in halide hybrid organic-inorganic halide perovskite materials used for photovoltaic application. Overall, the findings supported the targeted optimization of halide perovskite solar cells.
This work gives insights about the crystal formation and spatial heterogeneities on different length scales in halide hybrid organic-inorganic halide perovskite materials used for photovoltaic application. Overall, the findings supported the targeted optimization of halide perovskite solar cells.
In an in-situ study of the perovskite crystal formation, the photovoltaic performance along with optoelectronic properties are monitored in real time, identifying hitherto unknown stages in the crystallization process.
Solution-processed perovskite solar cells are prone to lateral inhomogeneities with detrimental influence on the device performance. Spatially resolved characterization techniques based on photoluminescence spectroscopy, light beam-induced current and thermography are employed to analyze non-uniform optoelectronic properties and quantify local loss mechanisms.
A subcell-selective analysis of monolithic two-terminal silicon perovskite tandem solar cells is presented, accessing the individual subcells by multi-wavelength photoluminescence spectroscopy.
