Despite the fact of the outstanding efficiency of the perovskite-based devices, their current size is around a few square millimeters. The application of this thin-film technology in module scale requires an interconnection with optimal laser processing to create a channel for the photo current. In this project, the relation between each film material and the laser beam is analyzed. Furthermore, this scribing process is applied to a workingmodule manufacturing. A semi transparent triple cation-based perovskite module scribing processing has been studied. An n-i-p structure was used for the device. 200 nm indium tin oxide films were used as the front and back electrode, to guarantee the transparency. Spin deposited layers of tin oxide and spiro- OMeTAD were used as the n-type and p-type layers, respectively. A buffer layer between the hole transmitting film and the anode was applied to enhance the performance; for this purpose, a 20 nm molybdenum oxide layer is vapor-deposited. This architecture had a performance of 10.95 % for a single cell, and 4.06 % for a six cells module in front illumination. The laser system is set to work in the UV range with 1 ps pulse length, 10 kHz frequency and apparent power from 1300 to 1800 for scribing speed between 30 to 60 mm/s. To further improve the performance of the module, it was illuminated from the rear side, achieving a 5.9 % efficiency. The results shows a promising outlook for this technology for novel applications, such was in tandem cell applications.
