The use of non-fullerene acceptors (NFAs) in organic solar cells has led to power conversion efficiencies as high as 18%<SUP>1</SUP>. However, organic solar cells are still less efficient than inorganic solar cells, which typically have power conversion efficiencies of more than 20%<SUP>2</SUP>. A key reason for this difference is that

Deping Qian, Zilong The open-circuit voltage of organic solar cells is usually lower than the values achieved in inorganic or perovskite photovoltaic devices with comparable bandgaps. Energy losses during charge separation at the donor–acceptor interface and non-radiative recombination are among the main causes of such voltage losses.

The power conversion efficiencies (PCEs) of organic solar cells (OSCs) using non-fullerene acceptors (NFAs) have now reached 18%. However, this is still lower than inorganic solar cells, for which PCEs >20% are commonplace. A key reason is that OSCs still show low open-circuit voltages (Voc) relative to their optical band gaps,
