In this paper the researchers compare the performance of fullerene and non-fullerene based solar cells fabricated with spin, blade or spray coating. They find that spin-coated device have higher performance and analyse it with drift-diffusion simulations of IV curves.

Paios was used to calculate Voc vs. L to substantiate more SRH recombination in spray coated device. They also used TPV and TPC to further substantiate their findings related to different aggregation.
