Abstract: An optoelectronic device comprising an active layer sandwiched between a first electrode and a second electrode. The active layer comprises a material of the formula AaBbMmXx, wherein A represents a monovalent inorganic cation, a monovalent organic cation, or mixture of different monovalent organic or inorganic cations; B represents a divalent inorganic cation, a divalent organic cation, or mixture of different divalent organic or inorganic cations; M represents Bi3+ or Sb3+; X represents a monovalent halide anion, or mixture of different monovalent halide anions; and a, b represent 0 or any positive numbers, m, x represent any positive numbers, and a+2b+3m=x.

Abstract: Sulfur-fused perylene diimides (PDIs) having the formula 2PDI-nS, wherein n is an integer. Such sulfur-fused PDIs (e.g., 2PDI-2S, 2PDI-3S, and 2PDI-4S) are incorporated as electron acceptors in an active region of a bulk heterojunction solar cell and/or as an electron transport layer. Example solar cells exhibit a power conversion efficiency above 5% and a fill factor above 70% (a record high for non-fullerene bulk heterojunction solar cell devices) when 2PDI-nS is used as the electron acceptor. In addition, the solar cells exhibit low open circuit voltage (Voc) loss.
