Title:
METHOD FOR CREATING SHUNT FREE TRANSLUCENT FLEXIBLE THIN-FILM PHOTOVOLTAIC MODULE
Document Type and Number:
WIPO Patent Application WO/2021/094481
Kind Code:
A8
Abstract:
A method for shaping a thin-film photovoltaic cell module from a photovoltaic cell sheet according to a predetermined contour of the module, where the cell sheet includes a flexible substrate based on a polymer or metal foil and a photovoltaic stack including one or more photo-active layers arranged on a front surface of the substrate. The method includes: providing the cell sheet, directing a laser beam towards a rear surface of the substrate; creating, by the laser beam, a trench in the rear surface, the trench shaped according to the contour such that the cell sheet is "divided" in a first portion within the contour and a second portion outside the contour; affixing a handling tool to one of the portions of the cell sheet on the rear surface of the substrate; selectively separating the portions by displacing the handling tool and one portion relative to the other portion.
