Summary: Organic photovoltaic technology (OPV) has achieved remarkable power conversion efficiencies (PCEs) in recent years. The synthesis of a new conjugated polymer called PATTD, based on a novel anthradithiophene and a commercially available dithienylbenzodithiophenedione, is reported in this study. The PATTD-based photovoltaic devices exhibit a PCE approaching 10% and excellent shelf-life stability, making it a promising candidate for commercial applications.

Summary: Solar-to-electrochemical energy storage is an important solar utilization technology, which includes solar cell and photocatalysis cell. While integrated solar batteries achieve indirect solar energy storage, the emerging coupled solar batteries allow direct solar energy storage. However, issues of rapid charge recombination and misaligned band energy have hampered the efficiency and development of coupled solar batteries. This review discusses the design of photoelectrochemical storage materials and coupled solar batteries to promote coupling between photogenerated charges and redox reactions for high efficiency, along with opportunities for new devices with matched band alignments.

Summary: Nonfullerene acceptor organic solar cells with power conversion efficiency up to 18% show the formation of NFA triplet exciton as a main non-radiative recombination and energy loss channel. Side-chain fluorination in high-efficiency NFA OSCs efficiently inhibits charge recombination to NFA triplet excitons, leading to higher V-OC and PCE. This paves the way for OSCs with lower V-OC loss and efficiency exceeding 20%.
