Back cover image: Organic solar cells (OSCs) are promising candidates for next-generation photovoltaic devices. However, conventional bulk heterojunction (BHJ) devices face inherent limitations in morphology control and phase separation. In article number CEY270070, Peng et al. systematically investigate the optimizing effects of nine halogenated functional additives for layer-by-layer (LbL) devices, identify the core performance advantages of 2-bromo-5-iodothiophene (20.12% PCE), analyzed the bromine-iodine synergistic effect and the donor-acceptor regulation mechanism of the thiophene core additive, balancing ease of processing with industrial application potential.
