(mentor) Degree granting institution Delft University of Technology Programme Electrical Engineering | Sustainable Energy Technology Date 2017-08-22 Abstract Despite the fact of the outstanding efficiency of the perovskite-based devices, their current size isaround a few square millimeters. The application of this thin-film technology in module scale requiresan interconnection with optimal laser processing to create a channel for the photo current. Inthis 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 frontand 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 holetransmitting film and the anode was applied to enhance the performance; for this purpose, a 20 nmmolybdenum oxide layer is vapor-deposited. This architecture had a performance of 10.95 % for asingle cell, and 4.06 % for a six cells module in front illumination. The laser system is set to work inthe UV range with 1 ps pulse length, 10 kHz frequency and apparent power from 1300 to 1800 forscribing speed between 30 to 60 mm/s. To further improve the performance of the module, it wasilluminated from the rear side, achieving a 5.9 % efficiency. The results shows a promising outlookfor this technology for novel applications, such was in tandem cell applications.
