Abstract

We introduce a facile method to generate aggregation-induced emission (AIE) properties in fused-ring electron acceptors through tetraphenylethylene decoration. Organic solar cells (OSCs) based on the AIE photovoltaic materials show decreased nonradiative energy loss during the energy conversion progress, with improvements in the open circuit voltage and device efficiency.
