Laser scribing of fluorine-doped tin oxide coated on glass substrate in air and water

•We examine the capability of five laser ablation techniques for scribing an FTO film.•A consistent cut with negligible burrs is made by using the flowing water technique.•Thermal damage is very small when the ablation is assisted by the flowing water film.•The suggested technique can be used for the P1 scribing of perovskite solar modules.
