METHOD OF MANUFACTURING THIN FILM PHOTOVOLTAIC PRODUCT

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 higher 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 lower absorption coefficient as compared to that of the second electrode layer. 公开了一种用于制造具有多个光伏电池的光伏产品的方法。该方法包括沉积具有第一和第二电极层(12、16)和设置在其之间的光伏层(14)的叠层。该方法包括分割叠层。该分割包括形成贯穿
