摘      要：For the process of photovoltaic conversion in organic solar cells(OSCs)and quantum-dot solar cells(QDSCs),three of four steps are determined by exciton behavior,namely,exciton generation,exciton diffusion,and exciton ***,it is of great importance to regulate exciton behavior in OSCs and QDSCs for achieving high power conversion *** to the rapid development in materials and device fabrication,great progress has been made to manage the exciton behavior to achieve prolonged exciton diffusion length and improved exciton dissociation in recent *** this review,we first introduce the parameters that affect exciton behavior,followed by the methods to measure exciton diffusion ***,we provide an overview of the recent advances with regard to exciton behavior investigation in OSCs and QDSCs,including exciton lifetime,exciton diffusion coefficient,and exciton ***,we propose future directions in deepening the understanding of exciton behavior and boosting the performance of OSCs and QDSCs.
