Hybrid metal halide perovskites have emerged as a potential photovoltaic material for low-cost thin film solar cells due to their excellent optoelectronic properties. However, high efficiencies obtained with lab-scale cells are difficult to replicate in large modules. The upscaling process requires careful optimisation of multiple steps, such as laser scribing which divides a module into serially connected cells using a pulsed laser beam. In this work, we characterise the effect of laser…
