In research, organic solar cells (OSCs) have received a lot of attention in recent years because of their low weight, non-toxicity, short energy payback times and high efficiencies. OSCs are also particularly intriguing to the industry because of their easy solution-based manufacturing technique, which allows for thin and flexible solar cells. The OSCs can be manufactured with different deposition technologies such as printing and spin-coating due to the solution-based fabrication process. Slot-die printing is a very promising printing approach because it is fast, causes low waste and is easily upscalable. Here, we optimize the slot-die printing technique of OSCs under ambient and nitrogen conditions and compare their attributes to spin-coated OSCs. The OSCs are compared using measuring techniques such as spectroscopy and real-space imaging in combination with X-ray scattering.
