20.500.12556/DKUM-86353 Efficiency of laser-shaped photovoltaic cells The main aim of this paper is to analyze the influence of laser shaping of the photovoltaic cell based on its efficiency. The authors described both process of the monocrystalline photovoltaic cell manufacturing, its efficiency, and the possibilities of usage in architecture and the process of creating the photovoltaic cells of unconventional shapes by using laser technology. A method for cutting photovoltaic cells using a fiber laser was presented as well as the parameters of the laser cutting process. The described method allows cutting the massively produced silicon cells according to the predetermined trajectory. Using the proposed process parameters, satisfactory cutting edge quality, and negligible impact of the laser beam on changes in the structure of the photovoltaic cell active layers were achieved. In each cycle of structure cutting, only a small part of the material is removed (from 1 to 2 mikro), and depending on the thickness, the process is repeated from 50 to 300 times. It has been shown that the efficiency of the modified cells depends on the ratio of their surface area to the laser cutting line. photovoltaic cells efficiency photovoltaic cell modification laser modification silicon cells fotovoltaične celice potencial modifikacija fotovoltaičnih celic laserska modifikacija silicijeve celice true false true MDPI Angleški jezik Slovenski jezik Znanstveno delo 2023-11-15 10:34:09 2023-11-15 10:36:08 2025-01-24 14:52:34 0000-00-00 00:00:00 2020 0 0 Str. 1-13 št. 18, št. članka 4747 Letn. 13 2020 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2020-06-29 2020-09-09 2020-09-11 621.38 28404483 10.3390/en13184747 1996-1073 Efficiency_of_laser-shaped_photovoltaic_cells_Korzeniewska_2020.pdf Efficiency_of_laser-shaped_photovoltaic_cells_Korzeniewska_2020.pdf 1 3F8D003B0A64AC46B15E92BEDFE86CB1 c30685c580fc03dc3cf08943899699a63ce67b1d9f09cc9fd4becf02868fb290 e5d2ffc6-839a-11ee-b01c-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=174164 https://doi.org/10.3390/en13184747 0 fd599b46-839a-11ee-b01c-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=174166 Fakulteta za energetiko Fakulteta za elektrotehniko, računalništvo in informatiko 0 0 0
