German scientists have improved the scribing method to interconnect perovskite PV cells, in order to then upscale them into mini PV modules. They established suitable laser fluence ranges for nanosecond and picosecond lasers and found that the former results in higher efficiency levels.Researchers from HTW Berlin and Helmholtz-Zentrum Berlin (HZB) have investigated the influence of the laser pulse duration for P3 patterning for interconnecting perovskite solar cells, so they can then upscale them into mini photovoltaic modules. They analyzed the electrical and compositional properties of the scribe ...Den vollständigen Artikel lesen ...
