BMWi Project Start: Pero4PV
03/2021 - Pero4PV - High throughput screening of lead-free Perovskites for photovoltaic applications - project started
Perovskite semiconductors are a class of materials with the potential to fundamentally change photovoltaics. However, the perovskite compounds with the best efficiencies and stabilities to date contain the element lead. Lead-free alternatives to these materials are of high commercial interest. To find lead-free analogs, a large material and process parameter space must be searched. Material databases already contain simulation data for possible suitable material combinations. However, efficient experimental screening of these materials has not been possible so far. In Pero4PV, database-driven high-throughput research is used to experimentally identify lead-free perovskite compounds for use in photovoltaics and to qualify them for their suitability in products. For this purpose, a stage-gate process is being developed in Pero4PV to successively characterize materials from solution to film to device. In addition, a fully automated setup for solar cell manufacturing based on liquid-processed perovskites with real-time process control to influence the microstructure is being developed. The setup will be used for screening, as well as for cell fabrication, for the purpose of stability studies.
As part of Pero4PV HI ERN is coordinating a joint effort together with Perovskite industry leader Oxford PV and the startup SCIPRIOS to take on the challenging task of screening large material spaces. The project is funded by the German Federal Ministry for Economic Affairs and Energy (BMWi) as part of the 8th Energy research framework program (FKZ: 03EE1092A). As part of the funding HI ERN receives almost 570.000 Euros over a period of 3 years.
