Abstract

A method for manufacturing a thin film solar cell device including a CIGS based thin film solar cell module (17). Edge deletion by selective removal of a multilayer structure (13) that includes at least a front contact (15) and a CIGS layer (7) to expose the back contact (5) in at least a peripheral area (22) in the circumferential region (21) of the module (17) adjacent to a first longitudinal thin film solar cell segment (18) allows for contacting of the module (17) by attaching at least a first contacting element (27) to the back contact (5). Preferably a blasting operation using simultaneous supply of blasting agents and gathering of debris in a blasting chamber (32) arranged on the thin film solar cell module (17) is used for the selective removal.
