Recent Advances of Furan and Its Derivatives Based Semiconductor Materials for Organic Photovoltaics

The state‐of‐the‐art bulk‐heterojunction (BHJ)‐type organic solar cells (OSCs) have exhibited power conversion efficiencies (PCEs) of exceeding 18%. Thereinto, thiophene and its fused‐ring derivatives play significant roles in facilitating the development of OSCs due to their excellent semiconducting natures. Furan as thiophene analogue, is a ubiquitous motif in naturally occurring organic compounds. Driven by the advantages of furan, such as...
