Revealing Hidden Dynamics in Patterned Perovskites
Perovskite solar mini modules rely on laser-structured regions to define electrically functional areas. While steady-state photoluminescence measurements can confirm the optical response of the active layer, they often provide limited insight into how laser processing affects local recombination dynamics and material properties.
Why Spatially Resolved TRPL Matters
Time-resolved photoluminescence (TRPL) imaging extends conventional TRPL measurements by combining temporal and spatial information across structured regions. This approach enables localized analysis of carrier dynamics and reveals photophysical variations that may remain hidden in point measurements alone.
Solira as an Integrated TRPL Platform
Solira was used to combine sample navigation, steady-state spectral characterization, and spatially resolved TRPL imaging within one measurement environment. This makes it possible to correlate where photoluminescence occurs, how it decays over time, and how local carrier dynamics change across laser-patterned regions.
