The direct write and non-contact nature of laser patterning is highly desirable as it is
compatible with integration in rollto-roll production lines. The reduced thermal effects of
ultrafast lasers are key to obtain selective removal of sensitive, thin film layers (< 0.2 µm). In
this work, diode-pumped solid state (DPSS) picosecond and femtosecond pulse duration
lasers are compared to identify the laser parameters and conditions required to produce
high efficiency organic photovoltaics.
