The emergence of nonfullerene acceptors (NFAs) has triggered a rapid advance in the performance of organic solar cells (OSCs), endowing OSCs to arise as a promising contender for 3rd generation photovoltaic technologies. Meanwhile, the ultimate goal of OSCs is to deliver cheap, stable, efficient, scalable, and eco-friendly solar-to-power products contributing to global carbon neutrality. However, simultaneously balancing these five critical factors of OSCs toward commercialization is extremely challenging. In this presentation, I will show the self-assembly strategy we developed to reduce the gap of high power conversion efficiency (PCE), long-term stability, green-solvent-processibility, scalability, and low cost of OSCs and demonstrate our green-solvent-processable and open-air-printable OSCs with simultaneously simplified device architecture and enhanced PCE, shelf, thermal as well as light illumination stability. Further, I will present our recent results on the outdoor degradation mechanism study in top-performing systems. Finally, I will summarize our findings on enhancing the commercial viability of OSCs toward commercialized cheap, stable, efficient, scalable, and eco-friendly OSCs.
