At PVcomB (Helmholtz-Zentrum Berlin), we are establishing a comprehensive data management framework for the outdoor testing of perovskite solar cells. A major bottleneck in materials science is the disconnection between synthesis data and long-term performance metrics. Addressing this, our initiative supports the increasing drive by research groups at HZB and partner institutes to introduce NOMAD (Novel Materials Discovery) directly into manufacturing laboratories, ensuring standardized metadata capture at the source.
We are deploying a scalable infrastructure to handle high-frequency time-series data from outdoor monitoring. The core innovation lies in the active integration with NOMAD: our system does not merely store testing data but links it to specific synthesis and manufacturing entries within the NOMAD repository. This linkage creates a "digital thread" that connects the initial synthesis conditions of a solar cell directly to its environmental performance and degradation history.
This prototype demonstrates a practical workflow for unifying the sample lifecycle. By bridging the gap between operational time-series databases and the rich metadata capabilities of NOMAD, we enable a feedback loop where synthesis parameters can be correlated with outdoor stability. This work serves as a blueprint for cross-institutional collaboration, moving towards a fully interoperable, FAIR-compliant data ecosystem where manufacturing and characterization processes actively "talk" to each other.
