Description: 
The introduction of low-band-gap polymer donors in organic bulk heterojunction solar cells allowed to achieve high power conversion efficiency (PCE)[1]. Such optimal performance are strongly correlated to the use of spin coating as technique to ensure reproducible and homogeneous films and chlorinated solvents that help the suitable nanoscale morphology. But this procedure is not industry compatible since spin coating does not allow large scale production and chlorinated solvents are poorly tolerated in workplaces since they are harmful towards environment and human health [2, 3]. For this reason, we realized high-performing inverted polymer solar cells by depositing all the layers through a scalable technique as spray coating [4] by using green solvents. We investigated the morphology at the interface between photoactive layer (PAL) deposited through a non-chlorinated solvent (ortho-xylene) and hole and …
