Patent number: 11869993Abstract: A method of forming a photovoltaic product with a plurality of photovoltaic cells is disclosed. The method comprises depositing a stack with first and second electrode layers (12, 16) and a photovoltaic layer (14) arranged in between. The method comprises partitioning the stack. The partitioning includes forming a trench (20) extending through the second electrode layer and the photovoltaic layer to expose the first electrode layer. The stack is first irradiated with a laser beam with a first spotsize and with a first wavelength for which the photovoltaic layer has a relatively high absorption coefficient as compared to that of the second electrode layer. The stack is then irradiated with a second laser beam with a second spotsize, greater than the first spotsize, and with a second wavelength for which the photovoltaic layer has a relatively low absorption coefficient as compared to that of the second electrode layer.Type: GrantFiled: July 9, 2020Date of Patent: January 9, 2024Assignee: Nederlandse Organisatie voor toegepast-natuurwetenschappelijk onderzoek TNOInventors: Veronique Stephanie Gevaerts, Johan Bosman
