Flexible Measurements Across Materials and Methods

Solira combines unmatched flexibility across materials and methods in one system that reduces time, space, and experimental complexity.

Solira is a flexible time-resolved photoluminescence microscope for advanced materials characterization. It combines several optical characterization methods in one system:

These methods provide insights into charge carrier dynamics, recombination pathways, and emission processes. Solira supports semiconductor research, nanomaterials characterization, the investigation of solar cells, LED characterization, and quantum emitter studies.

Flexible excitation and detection configurations adapt to varying sample properties, geometries, and signal conditions, while the upright microscope architecture supports a broad range of sample sizes and scanning approaches. By integrating spatial and temporal information within a single workflow, and enabling spectral analysis through optional coupling solutions, Solira delivers consistent, reproducible results that directly link microscopic processes to macroscopic device performance.

From Flexible Measurements to Real-World Insight

Laser patterning in perovskite solar mini modules can strongly influence local charge carrier dynamics and photoluminescence behavior. In a recent application study, Solira combined spatial localization, spectral characterization, and time-resolved photoluminescence imaging to investigate structured regions with high precision.

The results revealed measurable photoluminescence within laser-patterned areas, demonstrating that local material properties are modified rather than fully removed during processing. This workflow highlights how Solira enables spatially resolved insight into semiconductor devices by linking photophysical changes directly to material structure and device performance.
