Abstract
) and enhanced photocurrent density, attributed to an optimal balance between donor-acceptor interfacial area and charge transport pathways. Our findings reveal that both nanoparticle size and internal phase distribution critically influence photocatalytic performance, with smaller particles favoring short charge transport distance and larger particles benefiting from phase uniformity. This work establishes a comprehensive structure-property relationship that paves the way for the rational design of organic photovoltaic catalysts for efficient solar-to-hydrogen conversion.
