Abstract Organic photovoltaics have received active research interest during the past 30 years due to their low cost, flexibility, easy scalability, and robustness. Recently, several efforts been made enhance power conversion efficiency (PCE) stability by considering advanced photon harvesting technology, utilization of novel donor–acceptor materials, optimizing device design strategy. Specifically, multiplication process like singlet fission (SF) including low‐bandgap conjugated polymers non‐fullerene acceptors (NFA), led development organic with PCE close theoretical Shockley–Queisser (SQ) limit. Here, an up‐to‐date overview recent progress last five in a special focus on emerging techniques materials was reported. Further, various designing deployment strategies for these processes were explored along properties, challenges, achievements. Finally, strategy next‐stage directions analyzed proposed that could drive this field even further beyond laboratory reach final goal commercialization.
