Used as a non-fullerene acceptor in organic solar cells, Y6-BO-4F enhances light absorption and electron mobility, contributing to higher power conversion efficiencies. Its molecular design enables effective energy level matching with common donor materials, improving charge separation and reducing energy loss. Due to its strong near-infrared absorption, it broadens the solar spectrum utilization, making it ideal for high-performance tandem and single-junction photovoltaic devices. The chemical also supports solution processing, enabling low-cost, large-area fabrication of flexible solar cells.
