Laser-Scribing Patterning for the Production of Organometallic Halide Perovskite Solar Modules

Efficiencies of solar cells based on organometallic halide perovskite absorber material have dramatically increased over the past few years. Most of efficiencies reported so far have, however, been obtained on solar cells with very small lab-scale area of less than 0.3 cm(2). Only a handful of studies addressed the performances of minimodules based on perovskite, and all of them showed relatively large dead areas between the solar cell segments. In this study, we used laser-scribing techniques to pattern the module segment, reduce the dead area, and optimize the aperture area efficiency. The fraction of the dead area in the module is less than 16%, which proves that the laser-scribing technology can be adopted for monolithic serial interconnected perovskite modules and paves the way to improving module efficiency.
